Abstract

The (p, n) reactions on 54, 56Fe and 58, 60, 62, 64Ni have been studied at Ep = 35 MeV. Angular distributions of emitted neutrons leading to ground-state analogs and 2+ excited-state analogs were obtained for each target. Differential cross sections have been found to be consistent with the predictions obtained from DWBA calculations in which the Lane potential was employed. It was found that the direct process dominates at Ep = 35 MeV for the excitation of 2+ analogs. Their isoveetor deformation parameters are extracted from these isotope sets by comparison with the DWBA calculations. The magnitudes of the isoveetor deformation parameters are larger than the isoscalar parameters by a factor of 3 to 5, and are consistent with the calculated results in terms of the core polarization.
