    Abstract

    The fusion-evaporation reaction S32+Si28 at 125-MeV beam energy was used to populate excited states in Fe55. Combining the Gammasphere spectrometer with ancillary devices including the Microball CsI(Tl) array and a shell of neutron detectors, a comprehensive level scheme could be derived. The experimental results are compared with theoretical results from shell-model calculations. Taking into account isospin-symmetry breaking terms is found to considerably improve the shell-model description for Fe55. This motivated a predictive case study of near-yrast states in the mirror nucleus Cu55.
