Abstract
We systematically measured the differential cross sections of inelastic scattering off self-conjugate nuclei at two incident energies and at Research Center for Nuclear Physics, Osaka University. The measured cross sections were analyzed by the distorted-wave Born-approximation (DWBA) calculation using the single-folding potentials, which are obtained by folding macroscopic transition densities with the phenomenological interaction. The DWBA calculation with the density-dependent interaction systematically overestimates the cross sections for the transitions. However, the DWBA calculation using the density-independent interaction reasonably well describes all the transitions with –4. We examined uncertainties in the present DWBA calculation stemming from the macroscopic transition densities, distorting potentials, phenomenological interaction, and coupled channel effects in . It was found that the DWBA calculation is not sensitive to details of the transition densities nor the distorting potentials, and the phenomenological density-independent interaction gives reasonable results. The coupled-channel effects are negligibly small for the and states in , but not for the state. However, the DWBA calculation using the density-independent interaction at is still reasonable even for the state. We concluded that the macroscopic DWBA calculations using the density-independent interaction are reliably applicable to the analysis of inelastic scattering at .
