First printing of Bohr and Weisskopf's important paper on the influence of nuclear structure on the hyperfine structure of heavy elements in which they follow up Aage Bohr's suggestion two years earlier that internal structure of the deuteron might explain the theoretical discrepancy shown in the hyperfine structure of H2.
