Abstract

The fusion-evaporation reactions Si28(S32,1Î±2p1n)Fe53 at 125 MeV and Mg24(S32,2p1n)Fe53 at a 95-MeV beam energy were used to investigate excited states in Fe53. The combination of the Gammasphere Ge detector array and ancillary devices led to the construction of an extensive level scheme comprising some 90 transitions connecting 40 states. The lifetime of the yrast 25/2- state and upper limits for the lifetimes of a number of additional states were determined using the Cologne plunger device coupled to the GASP Î-ray spectrometer. The experimental results are compared to large-scale shell-model calculations using different sets of two-body matrix elements. In particular, predictions on electromagnetic decay properties such as lifetimes, branching ratios, and mixing ratios are studied in detail.
