摘要
The low-energy level structures of Mn-64(25)39 and Mn-66(25)41 were investigated through both the decay of Mn metastable states and the population of levels following the beta decay of Cr-64 and Cr-66. 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 pi p(3/2), nu p(1/2), and nu g(9/2) single-particle states, respectively.
