Mo94,96(C13,C12)Mo95,97reactions

Abstract
The levels of Mo95,97 below 1.2 MeV in excitation have been studied with the Mo94,96(C13,C12) reactions. Relative cross sections to the very closely spaced excited states were determined by particle-γ coincidence measurements. Generally excellent agreement between the measured cross sections and those calculated by a direct transfer code, which includes recoil correctly to first order, was found. The selectivity of this heavy-ion reaction was used to determine spin assignments which were ambiguous in light-ion experiments. The importance of two-step processes on the magnitude of the cross section was investigated. One state showed a strong enough deviation from distorted-wave Born-approximation calculations to suggest the influence of such two-step processes.
