Negative-Parity Band inV48

The electromagnetic decays of levels in ${}_{}{}^{48}{}_{}{}^{}\mathrm{V}$ have been studied via the reaction ${}_{}{}^{34}{}_{}{}^{}\mathrm{S}({}_{}{}^{16}{}_{}{}^{}\mathrm{O}, pn){}_{}{}^{48}{}_{}{}^{}\mathrm{V}$ at incident ion energies of 30-36 MeV. Spins, parities, and branching and mixing ratios were obtained from angular distribution, excitation function, $\gamma -\gamma$, and $n-\gamma$ coincidence measurements. Six, and possibly seven, members of a very pure rotational negative-parity band were identified. This band is based on a $1^{-}$ low-lying core excited state with probable configuration ${\left(\pi d_{\frac{3}{2}}\right)}^{-1\mathrm{}}{\left(\pi f_{\frac{7}{2}}\right)}^4{\left(\nu f_{\frac{7}{2}}\right)}^5$.
