Description
Excited states in $^{64,66}$Mn have been studied using in-beam $\gamma$-ray spectroscopy through knockout reactions from radioactive beams of $^{67,68}$Fe, respectively. The level schemes for the two odd-odd Mn isotopes have been established, exhibiting characteristics of quasi-rotational bands. Based on the systematics of the level structures in the lighter odd-odd Mn isotopes, the spin-parity of the levels and a $\pi f_{7/2} \otimes \nu g_{9/2}$ configuration have been proposed for the quasi-rotational bands in $^{64,66}$Mn, extending the quasi-rotational level structure to the most neutron-rich odd-odd Mn isotopes. The observed levels are compared with large-scale shell model calculations in the fpgd shell using the state-of-the-art LNPS effective interaction.
