Аннотация

The level scheme of $^{51}\mathrm{Mn}$ has been investigated using the $^{28}\mathrm{Si}(^{32}\mathrm{S},2\ensuremath{\alpha}1p)^{51}\mathrm{Mn}$ fusion-evaporation reaction at $125\phantom{\rule{0.3em}{0ex}}\mathrm{MeV}$ beam energy. The $\ensuremath{\gamma}$ rays were detected in the Ge-detector array Gammasphere, which was coupled to the $4\ensuremath{\pi}$-charged-particle detector Microball and the Neutron Shell for the coincident detection of evaporated particles. Over 100 new $\ensuremath{\gamma}$-ray transitions connecting some 50 excited states have been identified. Most of the states are built on particle-hole excitations across the shell gaps at particle number $N=Z=28$. The rich experimental data allows for a comprehensive comparison of core-excited states with results from large-scale shell-model calculations, which are known to provide excellent predictions for the lower-lying yrast and near-yrast levels in $1{f}_{7∕2}$ nuclei.
