초록

A record number of Sn-100 nuclei was detected and new isotopic species toward the proton dripline were discovered at the RIKEN Nishina Center. Decay spectroscopy was performed with the high-efficiency detector arrays WAS3ABi and EURICA. Both the half-life and the beta-decay end point energy of Sn-100 were measured more precisely than the literature values. The value and the uncertainty of the resulting strength for the pure 0(+) -> 1(+) Gamow-Teller decay was improved to B-GT = 4.4(-0.7)(+0.9). A discrimination between different model calculations was possible for the first time, and the level scheme of In-100 is investigated 6 further.
