First printing of Stern and Frisch's seminal paper with the very first measurement of the proton magnetic moment constituting the earliest experimental evidence for the internal structure of the nucleon. ""It is this work that was specifically mentioned in Stern's Nobel Prize citation"" (DSB) in 1943 when he was awarded the prize ""for his contribution to the development of the molecular ray method and his discovery of the magnetic moment of the proton"".""Dirac had promulgated a theory according to which the ratio of the magnetic moment of the proton to that of the electron should have been the same as the inverse ratio of their masses. This theory was believed so generally that when Stern, O. R. Frisch, and this writer began the very difficult experiments, they were told more than once by eminent theoreticians that they were wasting their time and effort. But Stern's perseverance paid off. Measurements showed a proton magnetic moment two or three times larger than expected.

It is this work that was specifically mentioned in Stern's Nobel Prize citation."" (DSB)The magnetic moment of the proton, first measured in 1933 by Frisch and Stern, was the earliest experimental evidence for the internal structure of the nucleon. Although the theory of strong interactions, Quantum Chromodynamics (QCD), is over 20 years old, a quantitative description of the magnetic moments of the nucleons based on QCD remains an elusive goal. The phenomenal quantitative success of the standard electroweak theory now allows one to use the weak interaction to obtain additional information on the magnetic properties of the nucleon. In particular, the measurement of the strength of the magnetic interaction with the neutral weak boson Z0(when combined with the usual magnetic interaction with the photon) enables a decomposition of the nucleon magnetism into the contributions arising from the three relevant quark flavors (up, down, and strange).
