Absorption of -Rays Excited in Cadmium by Slow Neutrons

Abstract

FLEISCHMANN¹ and Rassetti² have investigated the absorption of -rays excited in various elements by slow neutrons, and found quantum energies ranging from 2 × 10⁶ to 5 × 10⁶ e.v. When, however, -rays originate in a process of neutron fixation leading to the formation of a stable element, as, for example, in the case of cadmium, one would expect from mass-spectroscopic data essentially higher energies of the order of 10 × 10⁶ e.v.
