Abstract

The first evidence for excited states in 101In is presented. 101In is the lightest In isotope observed in an in-beam experiment. Two γ-ray transitions at 1309 and 341 keV, respectively, are strong candidates for a cascade to the ground state in this nucleus. In shell-model terms it has one proton hole and two neutron particles outside the double shell closure at 100Sn. New ideas for improving the peak to background ratio in certain γ-ray spectra from fusion evaporation reactions are introduced.
