Properties of excited states ofV49

Excitation energies, spins and lifetimes have been measured in ${}_{}{}^{49}{}_{}{}^{}\mathrm{V}$ employing the reaction ${}_{}{}^{46}{}_{}{}^{}\mathrm{Ti}(\alpha , p\gamma ){}_{}{}^{49}{}_{}{}^{}\mathrm{V}$ at a bombarding energy of 10.6 MeV. Reaction-produced protons were detected in an annular Si counter at an average angle of 171°. Coincident $\gamma$-ray spectra were measured with a Ge(Li) detector at angles ${120}^{°}\ge \theta \ge 0^{°}$. Two Ge(Li) detectors were used in a $\gamma -\gamma$ coincidence experiment. The half-life of the 90.7 keV excited state, $T_{\frac{1}{2}}=0.45\mathrm{}\left(3\right)\mathrm{}$ ns, was measured by time-delayed $n-\gamma$ coincidences employing the reaction ${}_{}{}^{46}{}_{}{}^{}\mathrm{Ti}(p, n\gamma ){}_{}{}^{49}{}_{}{}^{}\mathrm{V}$ at a proton bombarding energy of 2.1 MeV.
