Systematic analysis of 17,19F and 16,17O elastic scattering on 208Pb just below the coulomb barrier

Abstract

The 17F, 17O + 208Pb elastic scattering at 90.4 and 78 MeV (just below coulomb barrier), respectively, are analyzed within the framework of the double folding approach. The folded potentials are constructed by folding the density independent M3Y effective nucleon-nucleon interaction over the nucleon density distribution of 17F and its mirror 17O nuclei. Gaussian oscillator (GO) density distribution is considered to represent the (core16O+nucleon) structure for 17F and 17O. The knock-on exchange potentials are introduced to construct the real semi-microscopic potentials. The imaginary potentials are supplemented to derive potentials in two forms: either phenomenological Woods-Saxon (WS) or the same form as real folded potentials and different strengths. Moreover, the analysis of 19F, 16O + 208Pb elastic scattering at 91, 78 MeV energies, in that order, is applied in comparison to the 17F, 17O + 208Pb systems in an endeavor to investigate the behavior and properties of 17F and 17O projectiles.
