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.
