Berlin, Julius Springer, 1930. 8vo. Entire volume 63 of "Zeitschrift für Physik" bound in a contemporary half cloth with gilt title to spine. Library stamp to title-page. An overall fine and clean copy. Pp. 54-73. [Entire volume: VII, (1), 868 pp.].

First printing of Weisskopf and Wigner's landmark paper in which the introduced their seminal theory of spontaneous emission under QED.

"In a consecutive paper, Dirac applied second-order perturbation theory to the atom-field interaction and re-derived the kramers-Heisenberg formula for the scattering of light by atomic systems. Fner aspects of radiative processes, like line widths due to damping, required a more elaborate mathematical treatment [presented in the present paper]."
