Abstract

A terminating rotational band has been identified in $^{51} Mn$ following the $^{28} Si (^{32} S, 2 α {1 p)}^{51} Mn$ fusion-evaporation reaction at 130 MeV beam energy. Spins and tentative positive parities of the band members are assigned based on angular distribution and correlation measurements of transitions, which connect the rotational structure with previously known yrast states. Configuration-dependent cranked Nilsson-Strutinsky calculations suggest a configuration of the band, which comprises one particle in the ${1 g}_{9 / 2}$ intruder orbit.
