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