Elastic and inelastic scattering of 16O and 12C from A = 40−96 nuclei

Abstract

Angular distributions for the elastic scattering of 16O on 40, 48Ca, 50Ti, 52Cr, 54Fe, 58, 60, 62, 64Ni, 86, 88Sr 92, 96Zr, and 92Mo at, an incident energy of 60 MeV, 16O on 96Zr at 49 MeV, and 12C on 96Zr at 38 MeV have been measured. Inelastic scattering of 16O on 48Ca, 54Fe, 58Ni, 88Sr, 96Zr (60 MeV) and 12C on 96Zr (38 MeV) populating low-lying collective states of the target was also measured. The elastic scattering angular distributions are characteristic of those for strongly absorbed particles. The inelastic data show structure, however, which is found to be due to the destructive interference between Coulomb and nuclear excitation. The data are analyzed using the optical model with collective form factors. Deformation parameters in good agreement with those obtained by other means can be extracted provided corrections for the finite size of the projectile are made.
