Erste Ausgabe dieser bedeutenden Arbeit mit der Herleitung des Klein-Nishina-Wirkungsquerschnitts. "The Klein-Nishima formula played an important role in discussions of the applicable limits of quantum mechanics to studies of cosmic rays and nuclear physics" (DSB). - "In early 1928 Nishina returned to Copenhagen and worked with Oskar Klein. As a result of their cooperation, the Klein-Nishina formula was completed in October of the same year, before Nishina's return to Japan. In 1923 the quantum (particle) nature of X rays was discovered by Arthur Compton. Nishina had once made an experimental approach to this phenomena at the Cavendish Laboratory. The relation among the increased wavelength of the scattered X rays, the energy of recoiled electrons, and the scattering angle was accounted for by the quantum nature. In 1928 Nishina and Klein calculated the cross section and intensity of the Compton scattered radiation by the use of Dirac's new relativistic quantum mechanics of electrons. They succeeded in a complicated calculation by doing this separately and checking it together. (Nishina also brought this method of calculation with a team back to Japan.) Nishina and Klein searched for the solution of Dirac's wave equation in the case of a free electron (initially at rest) in the field of a plane electromagnetic wave" (DSB). - Titel einfach und Vorsatz mehrfach gestempelt.
