Role of virtual excitation in elastic and inelastic scattering Original Research Article

The influence of virtual excitation of unbound states in light nuclei on elastic and inelastic scattering is investigated. In particular, we elucidate the role of the breakup threshold energy in determining the effect of these excitations on the elastic scattering by fixing the energy at which the continuum begins. We also show that couplings between these unbound excited states play a major role in the inelastic scattering of View the MathML source from a 4He target.
