High-spin states in the odd-oddN=Znucleus50Mn

High-spin states in the odd-odd $N=Z$ nucleus ${}^{50}\mathrm{Mn}$ have been identified. At low spin, the $T=1\mathrm{}$ isobaric analogue states of ${}^{50}\mathrm{Cr}$ are established up to $I^{\pi }{=4\mathrm{}}^{+}.$ At high spin, the $T=0\mathrm{}$ band built on the low-lying $I^{\pi }{=5\mathrm{}}^{+}$ isomer in ${}^{50}\mathrm{Mn}$ becomes energetically favored and this band is observed up to its $f_{7/2}$-shell termination at $I^{\pi }{=15\mathrm{}}^{+}.$ Spherical shell model calculations in the full $\mathrm{pf}$ shell are found to be in excellent agreement with the experimental results. In addition, a weak side band in ${}^{50}\mathrm{Mn}$ is observed to spin ${(12\mathrm{}}^{-})$ and is interpreted as a possible octupole vibrational structure.
