Four-Body Effects in Nucleus-Nucleus Scattering

We develop a four-body CDCC (continuum discretized coupled channel) model, aimed at describing reactions where both nuclei present a low breakup threshold. The only inputs are the interactions describing the colliding nuclei, and the four optical potentials between the fragments. The method is applied to the (formula presented) and (formula presented) systems. We show that, in general, breakup channels are crucial to reproduce the elastic cross sections. We suggest that the present wave functions could be used in future DWBA calculations.SCOPUS: cp.p
