Abstract : The decay characteristics of Sr93 were examined by gamma-ray scintillation spectrometry and betaray proportional counting. A 7.8-min half-life was derived from the beta-ray decay data in agreement with literature values. The gamma-ray spectra yielded a 7.6 = 0.2-min half-life associated with the four most abundant gamma rays. The gamma-ray energies associated with Sr93 in the 0 to 2.56-Mev range are: 0.174, 0.257, 0.341, 0.451, 0.590, 0.717, 0.886, 1.02, 1.06, 1.09, 1.21, 1.66, 2.13, 2.18, and 2.46 Mev. The relative abundance of the prominent gamma rays are 0.174(30), 0.257(13), 0.590(83), 0.717(31), and 0.886 Mev (100). Evidence of the possible existence of Y93m was noted. (Author)
