Abstract: | Calculations of microscopic optical potentials (OPs) (their real and imaginary parts) are performed to analyze the 6
He + p elastic-scattering data at a few tens of MeV/nucleon (MeV/N). The OPs and the cross-sections are calculated using three model
densities of 6He . Effects of the regularization of the NN forces and their dependence on nuclear density are investigated. Also, the role
of the spin-orbit terms and of the non-linearity in the calculations of the OPs, as well as effects of their renormalization
are studied. The sensitivity of the cross-sections to the nuclear densities was tested and one of them that gives a better
agreement with the data was chosen. |
