The nuclear scattering at energies well above the Coulomb barrier allows for a fairly sensitive examination of the parameters of the optical potential when the relevant couplings are included into the calculations. In this work we present experimental angular distribution data for the elastic and inelastic scatterings of O16 impinging on Al27 and Si28 target nuclei at Elab=240MeV.

Experimental data are compared with coupled channel calculations with the inclusion of couplings to excited states in the target and projectile.

Abstract

The nuclear scattering at energies well above the Coulomb barrier allows for a fairly sensitive examination of the parameters of the optical potential when the relevant couplings are included into the calculations. In this work we present experimental angular distribution data for the elastic and inelastic scatterings of O16 impinging on Al27 and Si28 target nuclei at Elab=240MeV. The experimental data were measured at 7°<16° with good angular resolution. Experimental data are compared with coupled channel calculations with the inclusion of couplings to excited states in the target and projectile. We show that the shape of angular distributions are sensitive to the mass diffuseness parameter and the best agreement is achieved for a=0.62fm.
