Modelling scattering and resonances of weakly-bound radioactive nuclei

Abstract

For a theoretical description of weakly-bound systems studied with radioactive ion beams, it is important to make allowance for low-lying collective excited states of the colliding bodies which are not stable levels, but rather particle-emitting resonances. This work describes one such implementation in the framework of a multi-channel algebraic scattering formalism for determining nucleon-nucleus cross sections and spectra at low energies.
