Description
A microscopic and coherent description of nuclear structure and reactions is crucial to extend the predictivity of scattering observables, particularly for exotic nuclei that have not yet been discovered [1]. Optical potentials provide an effective way to decouple the nuclear structure many-body problem from the nuclear reaction few-body problem by constructing a projectile–target interaction.
We have developed a generator coordinate method (GCM) model based on an effective Hamiltonian [2]. Using this framework, we have calculated low-energy scattering properties for Mg and Cr isotopes, as reported in [3] and in an upcoming publication. This method provides the first viable way to calculate nuclear reaction observables from a microscopic structure model in heavy and deformed nuclei.
In this talk, I will illustrate the steps involved in constructing an optical potential for deformed nuclei from microscopic wavefunctions obtained with the projected GCM built on a Hartree–Fock–Bogoliubov basis.
