Abstract
The low-energy level structures of 2564Mn39 and 2566Mn 41 were investigated through both the decay of Mn metastable states and the population of levels following the β decay of 64Cr and 66Cr. The deduced level schemes and tentatively assigned spins and parities suggest the coexistence of spherical and deformed configurations above and below N=40 for the odd-odd Mn isotopes. The low-energy deformed configurations are attributed to the coupling between a proton in a K=1/2- level with neutrons in either the K=1/2- or the K=3/2+ levels originating from the πp3/2, νp1/2, and νg9/2 single-particle states, respectively.
