Abstract Thermal-neutron capture-gamma radiations for the V/sup 51/(n, gamma )V/ sup 62*/ reaction were observed with a fast-coincidenc e scintillation spectrometer recently developed for the Livermore 1-Mw pool-type reactor. The added-neutron binding energy in V/sup 52/ was measured as 7.30 plus or minus 0.05 Mev. and a decay scheme was established which verifies a previously proposed V/sup 51/(d,p)V/sup 52*/ level scheme. Several low-energy crossover, without stopover, transitions were observed: two from the 0.78-Mev level to the ground and 0.13 levels (the latter being the more intense) but not to the 0.42 level and one from the 0.83 Mev level to the ground state only. The 0.42-Mev level made both crossover and stopover transitions to the ground and 0.13-Mev levels (the former being the stronger). Some evidence exists to suggest that the low-lying V/ sup 52*/ states arise from excitations of the (lf/sup 7/2/ )/sup 3/ proton configuration alone. (auth)
