| Summary: | A modified version of the coupled-channel computer code CHUCK has been employed to calculate theoretical angular distributions for the inelastic scattering protons by 40 Ca, 90Zr, and 208Pb. Utilizing the vibrational collective model, with optical-model parameters generated by an optimized fit to the elastic data, angular distributions of differential cross-sections for excitations from the ground state to the first 3ˉ state of 40Ca, 90Zr and 208Pb have been calculated. These calculated angular distributions, for protons incident upon 40Ca at 135 and 160 MeV, 90Zr at 135 MeV, and 208Pb at 80, 121 and 160 MeV are compared to experimental data taken at the Indiana University Cyclotron Facility. Various treatments of the spin-orbit interaction have been investigated. Results of the study clearly demonstrate a breakdown of the collective model at higher energies of the incident projectile. |
