    Abstract

    The β decay of the N = 83 nucleus 131Cd has been studied at the RIBF facility at the RIKEN Nishina Center. The main purpose of the study was to identify the position of the 1 p3 / 2 and 0 f5 / 2 proton-hole states and the energies of core-excited configurations in the semi-magic nucleus 131In. From the radiation emitted following the β decay, a level scheme of 131In was established and the β feeding to each excited state determined. Similarities between the single-particle transitions observed in the β decays of the N = 83 isotones 132In and 131Cd are discussed. Finally the excitation energies of several core-excited configurations in 131In are compared to QRPA and shell-model calculations.
