THE THEORY OF PHOTOELECTRICITY

TAMM, IG. (+) S. SCHUBIN.

Zur Theorie des Photoeffektes an Metallen.

Berlin, Springer, 1931. 8vo. In contemporary halv cloth with gilt lettering to spine. In "Zeitschrift für Physik", Bd. 68, 1931. Entire volume offered. Stamp to front free end-paper and titlepage, otherwise fine and clean. Pp. 97-113. [Entire volume: VIII, 845 pp.].

First printing of Tamm and Schubin's important paper in which they showed that the external photoeffect is caused by the presence of a jump in potential on the border of the metal vacuum.

"In 1931 - 1933 Tamm studied the quantum theory of metals, specifically the external photoeffect in metals and the state levels of the electrons on the surface of the metal. His work with S. P. Shubin was the first to show that the external photoeffect is caused by the presence of a jump in potential on the border of the metal vacuum and is associated with the effect of surface absorption of light, while the optic absorption of light by the metal is associated with the volume effect."
