Gamow-Teller strength in the region of 100Sn.

New calculations are presented for Gamow-Teller beta decay of nuclei near [sup 100]Sn. Essentially all of the [sup 100]Sn Gamow-Teller decay strength is predicted to go to a single state at an excitation energy of 1.8 MeV in [sup 100]In. The first calculations are presented for the decays of neighboring odd-even and odd-odd nuclei which show, in contrast to [sup 100]Sn, surprisingly complex and broad Gamow-Teller strength distributions. The results are compared to existing experimental data and the resulting hindrance factors are discussed.
