GAMOW-TELLER STRENGTH IN THE REGION OF SN-100

New calculations are presented for Gamow-Teller beta decay of nuclei near Sn100. Essentially all of the Sn100 Gamow-Teller decay strength is predicted to go to a single state at an excitation energy of 1.8 MeV in In100. The first calculations are presented for the decays of neighboring odd-even and odd-odd nuclei which show, in contrast to Sn100, surprisingly complex and broad Gamow-Teller strength distributions. The results are compared to existing experimental data and the resulting hindrance factors are discussed. © 1994 The American Physical Society.
