Hardcover. Condition: Near Fine. BOHR, Niels; H.A. Kramers and J.C. Slater. "Uber die Quantentheorie der Strahlung", in Zeitschrift fur Physik, vol 24, Vieweg und Sohn/Springer, Berlin, 1924. The Bohr/Kramers/Slater paper is offered in the complete volume for 1924, (comprising vols 23 and 24) bound in one volume, (iv, 417pp + iv, 412pp), on pp 69-84 in vol 24. The volume Is very nicely bound in cloth and decorated paper-covered boards. This is ex-libris Pratt Library, Baltimore, with their bookplate and two rubber stamps on the interior, otherwise this is free and clear of any markings. Near-fine copy. [++] "The most striking feature of this remarkable paper, "The Quantum Theory of Radiation" ("Uber die Quantentheorie der Strahlung") was the renunciation of the classical form of causality in favor of a purely statistical description. Even the distribution of energy and momentum between the radiation field and the "virtual oscillators" constituting the atomic systems was assumed to be statistical, the conservation laws being fulfilled only on the average."--Complete Dictionary of Scientific Biography (online) This effort is also known as the "BKS Theory": The BohrKramersSlater theory (BKS theory) was perhaps the final attempt at understanding the interaction of matter and electromagnetic radiation on the basis of the so-called old quantum theory, in which quantum phenomena are treated by imposing quantum restrictions on classically describable behaviour. It was advanced in 1924, and sticks to a classical wave description of the electromagnetic field. It was perhaps more a research program than a full physical theory, the ideas that are developed not being worked out in a quantitative way."--Wikipedia.

Braunschweig, Berlin, Vieweg & Sohn u. Julius Springer, 1924. 8vo. Bound in contemporary halfcloth. In "Zeitschrift für Physik", Bd. 24. (Entire volume offered). A stamp on titlepage otherwise fine and clean. Pp.69-87. [Entire volume: IV,412 pp]. 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)."In an effort to reconcile the particulate and wavelike properties of radiation, Bohr, Kramers, and Slater in 1924 formulated a new quantum theory of radiation. According to their hypothesis, momentum and energy-are conserved only statistically in interactions between radiation and matter." (DSB).The present paper became a great influence to Bothe and his Compton collisions and the Coincidence method which eventually resulted in him being awarded the Nobel Prize in Physics.
