Abstract

A gamma ray of 0.878 MeV was found in the decay of Sr85 in addition to the well-known 0.514-MeV gamma ray. The half-lives of both gamma rays were measured. The half-life of the 0.878-MeV gamma ray was found to be 64.9±1.99 days and the half-life of the 0.514-MeV gamma ray was found to be 63.9±0.27 days. There is good evidence of a gamma ray of 0.356±0.015 MeV in coincidence with the 0.514-MeV gamma ray. The 0.878-MeV gamma ray has also been found to be in coincidence with the characteristic x ray of Rb due to orbital electron capture. The relative intensities of the 0.878-, 0.356-, and 0.514-MeV gamma rays are about 1.07×104, 0.2×104, and 1.0, respectively. A decay scheme is proposed on the basis of these results.
