Summary In the years 816-819, a series of councils was held at the imperial palace in Aachen. The goal of the meetings was to settle a number of questions about ecclesiastical organization. These issues were hotly debated throughout the Christian Roman Empire of the fourth and fifth centuries, and then reinvigorated by the renewal of empire under Charlemagne and his son Louis the Pious. At the centre of the ensuing debate stood the distinction between monks and monastic communities on the one hand, and the so-called clerici canonici and their communities on the other. Many other reforms were proposed in its wake: the position of the episcopacy needed to be renegotiated, the role of the imperial court needed to be consolidated, and the place of every Christian within the renewed Carolingian Church needed to be redefined. What started out as a seemingly straightforward reorganisation of the religious communities that dotted the Frankish ecclesiastical landscape thus quickly turned into a broad movement that necessitated an almost complete categorization of the orders of the Church. The contributions to this volume each zoom in on various aspects of these negotiations: their prehistory, their implementation, and their influence. In doing so, previously held assumptions about the scope, the goals, and the impact of the 'Carolingian Church Reforms' will also be re-assessed.

Summary Note: the full text of this volume is now available in Open Access at: https://www.brepolsonline.net/action/showBook?doi=10.1484/M.CELAMA-EB.5.118545 This volume explores the extent to which the reinstitution of the Empire in Western Europe brought about new ways of reconciling the multitude of post-Roman identities with the way the past was shaped in historiographical narratives. From universal histories to local chronicles, and from narratives that support Carolingian rule to histories with a more local focus, the centralization of power and authority in the course of the eighth and ninth centuries forced those who engaged with their own past and that of their community to acknowledge the new situation, and situate themselves in it. The contributions in this volume each depart from a single source, event, or community, and relate their findings to the broader issue of whether the rise of the multi-ethnic Carolingian court allowed for more inclusive narratives to be created, or if their self-proclaimed place at the centre of the Frankish world actually created a context in which local communities were given new tools to assert themselves.

Volume LIII. (1908-09). Entire volume offered. The volume contains 24 papers, all with seperate pagination. Rutherford's paper: pp. 1-3.
First printing of the paper which Rutherford and Royds gave the final proof that the alpha particle are atoms of helium. The present paper was read on November 3rd 1908 and published on the 19th. It was reprinted in Philosophical Magazine and that paper is dated November 13, 1908 and published February 1909.""After nearly a decade of labor, Rutherford was finally prepared to state... what the alpha particle really was ""We may conclude that an alpha-particle is a helium atom, or, to be more precise, the alpha-particle, after it has lost its positive charge, is a helium atom"". In a paper together with Royds, completed in November 1908, he was even more emphatic: ""We can conclude with certainty... that the alpha-particle is a helium atom... They had shown that a discharge sent through a volume in which alpha-particles from radium had been collected produced the characteristic helium spectrum !""(Pais ""Inward Bound"", p. 61).""Rutherford’s early conviction that the alpha particle was a doubly charged helium atom, but he had not succeeded in proving that belief. In 1908 he and Geiger were able to fire alpha particles into an evacuated tube containing a central, charged wire and to record single events. Ionization by collision, a process studied by Rutherford’s former colleague at Cambridge, J. S. E. Townsend, caused a magnification of the single particle’s charge sufficient to give the electrometer a measurable ""kick."" By this means they were able to count, for the first time accurately and directly, the number of alpha particles emitted per second from a gram of radium.This experiment enabled Rutherford and Geiger to confirm that every alpha particle causes a faint but discrete flash when it strikes a luminescent zinc sulfide screen, and thus led directly to the widespread method of scintillation counting. It was also the origin of the electrical and electronic methods of particle counting in which Geiger later pioneered. But at this time the scintillation technique, now proved reliable, was more convenient. This counting work also led Rutherford and Geiger to the most accurate value of the fundamental electric charge e before Millikan performed his oil-drop experiment. They measured the total charge from a radium source and divided it by the number of alphas counted to obtain the charge per particle. Since this figure was about twice the previous values of e. they concluded that the alpha was indeed helium with a double charge. But Rutherford still desired decisive, direct proof"" and here his skilled glassblower came to his aid. Otto Baumbach in 1908 was able to construct glass tubes thin enough to be transparent to the rapidly moving alpha particles yet capable of containing a gas. Such a tube was filled with emanation and was placed within a larger tube made of thicker glass. In time, alpha particles from the decaying emanation penetrated into and were trapped in the space between inner and outer tubes: and when ROYDS SPARKED THE MATERIAL IN THIS SPACE, THEY SAW THE SPECTRUM OF HELIUM.""

Tuomikoski ""Differences in the Decay of the Radium Emanations"" (issued April 7th, 1909).

First apperance of this famous lecture in which Rutherford predicted the existence of a new constituent of the atomic nucleus and its likely properties. In the lecture Rutherford suggested that ""it may be possible for an electron to combine much more closely with the H-nucleus (than is the case in the ordinary hydrogen atom)... It is the ontentionof the writer to test (this idea)... The existence of such atoms seems almost necessary to explain the building up of heavy elements.""Rutherford's collegue Chadwick made several attempts to detect the neutral particle but none was successful until he learned of experiments by the Joliot-Curies in Paris, in which, they said, extremely penetrating gamma rays were emitted. As he suspected, Chadwick found the rays were not gammas but neutrons: and not long afterward Norman Feather, also at the Cavendish, showed that neutrons were capable of causing nuclear disintegrations. Chadwick gave proof of its existence in 1932.

Rutherford's paper: pp. 537-587.
First appearance of this seminal paper which contains Rutherford's discovery of artificial transmutation. He here discovered, that the atomic nucleus (discovered by him in 1911) itself had a structure, when, by bombarding nitrogen with alpha particles, he produced THE FIRST ARTIFICIAL TRANSFORMATION OF AN ELEMENT INTO ANOTHER, and what was left after the bombardment had to be those of oxygen atoms. - Thus thus began the age of nuclear physics.""Rutherford was .. the first man ever to change one element into another as a result of the manipulations of his own hands. He had achieved the dream of the alchemists. He had also demonstrated the first man-made ""nuclear reaction"". By 1924 Rutherford had managed to knock protons out of the nuclei of most of the lighter elements."" (Asimov).""A few years before, Marsden had noticed scintillations on a screen placed far beyond the range of alpha particles when these particles were allowed to bombard hydrogen. Rutherford repeated the experiment and showed that the scintillations were caused by hydrogen nuclei or protons. This was easily understood, but when he substituted nitrogen for the hydrogen, he saw the same proton flashes. The explanation he gave in 1919 stands beside the transformation theory of radioactivity and the nuclear atom as one of Rutherford’s most important discoveries. This, he said, was a case of artificial disintegration of an element. Unstable, or radioactive, atoms disintegrated spontaneously"" but here a stable nucleus was disrupted by the alpha particle, and a proton was one of the pieces broken off."" (DSB).PMM: 411.

First appearance of the paper in which Rutherford set forth his early - before 1911-model - model of the atom, the so-calles Saturnian Model. Rutherford pictured here the radioactive atom as a giant whirligig of electrons and alpha-particles, whose stability is somewhat disturbed, perhaps as a result uncompensated radiation losses, precipitating the expulsion of some of its constituents with the tremendous speeds they possessed befiore the explosion.

First edition and first printing of all three papers. Rutherford, in this paper for the first time identifies the hydrogen nucleus, and called it the 'positive electron'. He later called it 'the proton' . In his definitive paper of 1911 he estimated the radius of the nucleus, a hundred thousand times smaller than that of an atom. Darwin in his paper (offered here) gave a more precise measure.In the first lines of the paper Rutherford outlines the content ""The present paper and and the accompanying paper by Mr. C. Darwin (the second paper offered here) deal with certain points in connection with the ""nucleus"" theory of the atom which were purposely omitted in my first communication on that subject (Phil. Mag. May 1911). A brief account is given of the later investigations which have been made to test the theory and of the deductions which can be drawn from them. At the same time a brief statement is given of recent observations on the passage of alpha particles through hydrogen, which throw importent light on the dimensions of the nucleus."" - Rutherford had studies alpha-particles intensely in the years before 1914 and proved quite conclusively that the individual particle was a helium atom with its electrons removed. The alpha particles were like the positive rays that had been discovered by Goldstein (1886), and now in 1914 (the paper offered) Rutherford suggested that the simplest positive rays must be those obtained from the hydrogen and that these must be the fundamentall positively-charged particle. He names it a 'positive electron'.Darwin, in the paper offered ""concluded from the known data:""No force proportional to some power of the distance other than the inverse square can give the dependence (the Rutherford scattering cross section) on (the initial velocity)"", and he then calculated the distance of closest alpha-particle-nucleus approach.The paper by Niels Bohr relates to ""The Stark effect"". In 1913 appeared ""an importent new discovery: when atomic hydrogen is exposed to a static electrical field its spectral lines split, the amount of splitting being proportional to thefield strenght (the linear Stark effect). After Rutherford read this news in ""Nature"", he at once wrote to Bohr:'I think it is rather up to you at the present time to write something on....electric effects.'"" (A. Pais). Bohrs paper on The Stark effect appeared in 1914, the paper offered here. - Rosenfeld. Niels Bohr' publications No. 10).

During his first spell at the Cavendish Laboratory, he invented the detector for electromagnetic waves, an essential feature being an ingenious magnetizing coil containing tiny bundles of magnetized iron wire. The detector made it possible to send wireless signals.
