The Theory of Atomic Spectra.

First edition of this definitive exposition, "a bible on the subject from the moment of its 1935 publication" (Wheeler, p. 112). It remained the standard reference of atomic spectroscopy for much of the 20th century. This work is scarce in the jacket. Condon (1902-1976) was a nuclear physicist and pioneer of quantum mechanics who was involved in the development of both radar and atomic weapons during the Second World War. "Condon's multidimensional career spanned fundamental contributions to atomic theory and spectroscopy, guidance of industrial and governmental application of those scientific principles, and, finally, action as a voice of conscience in the control of the power of atomic energy and commitment to the practice of science in the public interest" (ANB). John Archibald Wheeler, Geons, Black Holes, and Quantum Foam: A Life in Physics, 1998. Large octavo. Tables and diagrams throughout. Original blue cloth, spine lettered in gilt.
