The
β
decay of the
N
= 83 nucleus
131
Cd 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

proton-hole states and the energies of core-excited configurations in the semi-magic nucleus
131
In. From the radiation emitted following the
β
decay, a level scheme of
131
In 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
132
In and
131
Cd are discussed. Finally the excitation energies of several core-excited configurations in
131
In are compared to QRPA and shell-model calculations.
