Systematic calculations of reactions with exotic and stable nuclei to establish a unified theoretical approach

Abstract

This manuscript reports on systematical optical model (OM) and continuum discretized coupled channel (CDCC) calculations applied to describe the elastic scattering angular distributions of exotic and stable nuclei projectiles on heavy targets. Our optical potential (OP) is composed by the nuclear microscopic double folding São Paulo potential (SPP), derived from the non-local nature of the interaction, and the Coulomb dipole polarization (CDP) potential, derived from the semi-classical theory of Coulomb excitation. The OP is compared to the trivial equivalent local potential (TELP), extracted from CDCC calculations. The OM and CDCC predictions corroborate each other and account for important differences in the nuclei reaction mechanisms, which are directly related to their structural properties. Thus, OM and CDCC establish a common basis for analysing or even predicting on exotic and stable nuclei reactions.
