Microscopic optical potentials for composite particle scattering at low energies

Abstract

The evaluation of microscopic alpha-nucleus optical potentials within the nuclear structure approach is revisited. This approach seems best suited at low energies relevant for nucleosynthesis, but no further developments were performed for more than two decades. Here, a report on the first steps of a revival of the nuclear structure approach, i.e. numerical implementation of the formulae for the imaginary part, is given.
