Decay of Sr⁸³

Abstract

The disintegration of Sr⁸³ produced by (γ, n) reaction was studied with the aid of scintillation spectrometer. The gamma-ray spectra showed lines at 40, 385 and 755 keV. And the analysis of the beta-ray spectra defined two groups of beta-ray of the end-point energy of 0.81 and 1.15 MeV. The decay scheme was proposed from the information of the single and coincidence scintillation spectra. In the decay scheme, the 40-, 385- and 755-keV levels were established and the spin and parity assignments of ground and first excited 40-keV levels were confirmed to be 5/2- and 3/2-, respectively.
