American Physical Society

IN recognition of his advances in theoretical physics which have led to a better understanding of the structure of the atomic nucleus, Aage Bohr of the Institute for Theoretical Physics in Copenhagen was honored by the American Physical Society and the American Institute of Physics on April 27 when he became the second recipient of the Dannie Heineman Prize in Mathematical Physics. Prof. Bohr, who received the award at the banquet held by the Physical Society during its annual spring meeting in Washington, D.C., was cited for his contributions in two particular areas of nuclear theory: (1) his investigations of the interaction of the nucleus with the electron shell, which have made nuclear spectroscopy a new tool in the study of atomic structure, and (2) his development, in collaboration with B. R. Mottelson, of the theory of nuclear rotations and vibrations, which has led to a deeper understanding of nuclear spectroscopy and has rejuvenated nuclear physics by giving rise to a wealth of new systematic investigations.
