Large-scale shell model calculations have been carried out for odd-odd 58-62Mn isotopes in two different model spaces. The first set of calculations has been carried out in full fp shell valence space with two recently derived fp shell interactions namely GXPF1A and KB3G treating 40Ca as core. The second set of calculations has been performed in the fpg 9/2 valence space with the fpg interaction treating 48Ca as core and imposing a truncation by allowing up to a total of six particle excitations from the 0f 7/2 orbital to the upper fp orbitals for protons and from the upper fp orbitals to the 0g 9/2 orbital for neutrons. For low-lying states in 58Mn , KB3G and GXPF1A both predict good results and for 60Mn , KB3G is much better than GXPF1A. For negative-parity and high-spin positive-parity states in both isotopes the fpg interaction is required. Experimental data on 62Mn is sparse and therefore it is not possible to make any definite conclusions. More experimental data on negative-parity states is needed to ascertain the importance of 0g 9/2 and higher orbitals in neutron-rich Mn isotopes.
