Application of the Bruyères Jeukenne-Lejeune-Mahaux model potential to composite nuclei with a single-folding approach.

A single-folding (SF) model analysis has been performed for α and deuteron elastic scattering from 58Ni, 90Zr, 116Sn, and 208Pb at incident energies between 10 and 100 MeV/nucleon with the Lane-consistent Bruyères Jeukenne-Lejeune-Mahaux model nucleon-nucleus potential. The energy dependence of a set of only three potential parameters was derived, and the resulting global optical model potentials were found to account well for α and deuteron elastic scattering within their studied energy ranges. The energy dependence of a real potential form factor is found to be important for describing α-nucleus scattering within large energy ranges. Corrections due to the compositeness of projectiles to the SF potentials were studied and were compared with theoretical estimations through the renormalization factor. Systematic differences in renormalization factors between α particles and deuterons were observed. [ABSTRACT FROM AUTHOR]
