Influence of Nuclear Structure on the Hyperfine Structure of Heavy Elements.

Lancaster, American Institute of Physics, 1950. Lex8vo. In the original printed wrappers. Entire volume 77, January 1 of "The Physical Review". A small nick to spine, otherwise a fine and clean copy. Pp: . [Entire volume: Pp. ix, (1), 1100.]. 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.
