ResumoLevel structures in $^{61,62}\mathrm{Mn}{}_{36,37}$ were studied with Gammasphere in the reaction of a $430$-MeV $^{64}\mathrm{Ni}$ beam and a thick $^{238}\mathrm{U}$ target. The newly identified levels decrease in excitation energy compared to the analogous structures in the lighter Mn isotopes and behave similarly to states in the corresponding Fe isotones that involve ${g}_{9/2}$ neutron excitations. This behavior illustrates the importance of the inclusion of the $\ensuremath{\nu}{g}_{9/2}$ orbital in any realistic shell-model calculations in this region.
