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 0.17430, 0.25713, 0.59083, 0.71731, and 0.886 Mev 100. Evidence of the possible existence of Y93m was noted. Author
