An Investigation of the Products of the Disintegration of Uranium by Neutrons

Abstract

Products of uranium fission which are chemically antimony, tellurium and iodine have been examined. The following activities have been found: Three activities—the 10-hour tellurium, the 70-minute tellurium, and the 8-day iodine—have been identified with known bodies through comparison of half-lives and beta-ray spectra. Genetical relationships of the activities have been established by a technique of periodic separations and by the observation of growth in activity curves.
