Microscopic optical potentials from a Greens function approach

Abstract: Optical potentials are a standard tool in the study of nuclear reactions, as they describe the effective interaction between a target nucleus and a projectile. The use of phenomenological optical potentials built using experimental data on stable isotopes is widespread. Although successful in their dedicated domain, it is unclear whether these phenomenological potentials can provide reliable predictions for unstable isotopes. To address this problem, optical potentials based on microscopic nuclear structure input calculations prove to be crucial, and are an important current line of research. In this work, we present a new approach for the systematic derivation of optical potentials using input from nuclear structure models. We provide an application addressing the n+24Mg elastic scattering reaction based on the valence shell model.
