Optical model dependence of the reaction 24Mg(16O,12C)28Si

An attempt is made to understand the dependence of angular distributions for α-transfer reactions between heavy ions on the optical potential, using semiclassical concepts. Angular distributions are calculated semi-classically for the reaction 24Mg(16O,12C)28Si at 56 MeV and 48 MeV laboratory energies using two different optical potentials. The l-dependence of the partial wave amplitudes is examined in each case. An interesting by-product of the calculation is that the probability of transfer is maximum for the separation of the interacting nuclei greater than the 'grazing distance' by the order of the α-particle radius.
