THE DECAY OF Sb¹²⁵

Abstract

The beta, internal-conversion, and gamma radiations of Sb 125 –Te 125 have been examined with magnetic and scintillation spectrometers, and by means of beta–gamma and conversion electron–gamma coincidence techniques. The results lead to self-consistent transition intensities, and completely support the decay scheme and spin–parity assignments of Narcisi (1958). There is evidence that a considerable fraction of the 633-keV radiation may originate at the 668-keV level. There is also supporting evidence for the 62-keV transition reported by Chandra and Pandharipande (1963).
