Convergence of the solution of the continuum discretized coupled channels method

The validity of the method of continuum discretized coupled channels (CDCC) is numerically tested and confirmed for a realistic example of [Formula Presented] scattering at 80 MeV. Elastic and breakup S-matrix elements, calculated with the CDCC method, numerically converge as the model space is extended, viz., the internal angular momentum of the proton-neutron pair and the matching radius are increased. Two methods of discretization, the average method and midpoint method, of the continuum of the internal linear momentum of the [Formula Presented] pair are tested and found to yield the same results.
