BOHR, NIELS, H.A. KRAMERS, J.C. SLATER. - TOWARDS QUANTUM MECHANICS.

Über die Quantentheorie der Strahlung. (The quantum theory of radiation).

Braunschweig, Berlin, Vieweg & Sohn u. Julius Springer, 1924. 8vo. Contemp. hcloth. In: Zeitschrift für Physik", Bd. 24. IV,412 pp. (Entire volume offered). The paper: pp. 69-87. A stamp on titlepage. Clean and fine.

First apperance (simultaneously printed in Philosophical Magazine) of a fundamental paper in the development of the Quantum Theory, as it here was set forth three fundamental ideas: 1. Slater's idea of 'a Virtual radiation field', 2. statistical conservation of energy and momentum, and 3. statistical independence of the processes of emission and absorption in distant atoms. (See Van der Waerden "Sources of Quantum Mechanics" No. 5).
