Inelastic Proton Scattering from Vanadium

Abstract

The low-lying excited states of ${\mathrm{V}}^{51}$ have been investigated by means of inelastic proton scattering. Protons were accelerated to 6.0, 7.0, and 7.4 Mev in the MIT-ONR electrostatic generator, and the scattered protons were analyzed with a broad-range magnetic spectrograph, observations being made at 90 and 130 degrees to the incident beam. Proton groups were found which corresponded with levels in ${\mathrm{V}}^{51}$ at 0.322±0.002, 0.931±0.003, 1.614±0.005, and 1.819±0.05 Mev. A large number of lower energy groups were observed, which are associated with excited states between 1.85 and 4.50 Mev. Two groups of alpha particles were also observed and assigned to the ground state and first excited state formed in the ${\mathrm{V}}^{51}(p, \alpha ){\mathrm{Ti}}^{48}$ reaction ($Q=1.161\mathrm{} \mathrm{and} 0.167$ Mev).
