Abstract

Excited states in the neutron-rich isotopes ${}^{57 - 60}{Mn}$ have been studied with fusion-evaporation reactions induced by ${}^{48}{Ca}$ beams at $130$ MeV on ${}^{13, 14}C$ targets. Level schemes have been deduced reaching spins of $~ 16 ℏ$ and $~ 27 ℏ / 2$ in the odd-odd and odd-even isotopes, respectively. States with natural parity within an $fp$ model space are compared to the predictions of large-scale shell-model calculations using the recently developed GXPF1A effective interaction. Quasirotational structures are evident in all of the isotopes and are discussed in terms of the deformation-driving potential of the $ν 1 g_{9 / 2}$ intruder orbital. It is apparent that an enlarged model space, incorporating at least the $1 g_{9 / 2}$ intruder state, is necessary to reproduce the observed experimental systematics in a more satisfactory manner.
