1930. Sommerfeld, Arnold (1868-1951) and G. Schur. Über den Photoeffekt in der K-Schale der Atome, insbesondere über die Voreilung der Photoelektronen. Offprint from Annalen der Physik, 5th series, 4 (1930). 419-449pp. 225 x 145 mm. Without wrappers as issued. Small tears in paper backstrip, light toning but very good. First Edition, Offprint Issue. “In 1929 Arnold Sommerfeld and G. Schur carried out a systematic wave mechanical calculation of the effect of radiation pressure (i.e., of the action of the electric and magnetic fields of the incident radiation) (truncated) on the intensity distribution of the photoelectrons. In particular, they found that Wentzel’s formula . . . which he had obtained by simply considering the momentum of the incident light-quantum—must be improved” (Mehra & Rechenberg, Erwin Schrödinger and the Rise of Wave Mechanics, p. 838[n]). Gregor Wentzel had published the formula in his paper “Über die Richtungsverteilung der Photoelektronen” (Zeitschrift für Physik 41 [1927]: 828-832). . (Inventory #: 50952)
