Nuclar Data Sheets for A = 83

The 1966 version of Nuclear Data Sheets for A = 83 was revised on the basis of experimental data received prior to November 1, 1974. Information from approximately 90 papers and communications was included in the present evaluation. Data on nine A = 83 nuclei are presented. This A-chain is characterized by a paucity of reaction data compared with radioactive decay data. For 83Ge only the half-life is known. For 83As, the half-life is known but few details of the decay scheme have been determined. The decay schemes of the 83Se ground state and first-excited state are reasonably well established, and levels in 83Se are known from (d,p). The decay schemes of 83Br and 83Rb are well established, and these decays give all adopted information on levels in stable 83Kr. The complex decay scheme for 83Sr is reasonably well established, which leads to all information on levels in 83Rb. Information on 83Sr levels is obtained from 83Y decays and (d,t). The decay schemes for two 83Y isomers have been reasonably well determined, but the ordering of the isomers is not known. The compilers regard the identification of 83Zr as uncertain. This compilation is divided into three parts appearing in the following order: Drawings, Sheets, References. (U.S.)
