THE DECAY OF Sb125

Abstract

The beta, internal-conversion, and gamma radiations of Sb¹²⁵–Te¹²⁵ 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).
