Abstract :
In two complementary measurements, an array of high-resolution germanium detectors and a total-absorption γ-spectrometer were used to investigate the β decay of 102In, a one proton–hole, three-neutron particle nucleus with respect to the 100Sn core. A total of 509 β-delayed γ rays (494 new) were observed for 102In, and a scheme comprising 234 levels (223 new) was constructed for the decay daughter 102Cd. The QEC value of the decay and the half-life were determined, the latter one being 23.3(1) s. The summed Gamow–Teller strength deduced from the high-resolution experiment is as low as 0.60±0.07±0.11 compared to a value of 4.70±0.05±0.20±1.0 obtained from the total absorption measurement, and to a shell-model prediction of 13.3.
