• In order to settle the question on the model-space dependence of a model-space solution to a single three-body Lippmann-Schwinger (LS) equation, we carry out a carefully conducted calculation on a simplified deuteron + nucleus scattering. In this calculation, real potentials of surface-delta forms are used for nucleon-nucleus interactions, and no bin-averaging procedure of the CDCC approach is employed. The resulting elastic and breakup t-matrix elements show rapid convergence regardless of the presence or absence of rearrangement channels. They show no sign of suspected sustained dependence on the model space. Thus, the model-space solution appears to be truely unique. The conclusion drawn is quite general despite the use of surface delta interactions. We further prove that the model-space solution satisfies automatically the boundary conditions at the origins of rearrangement channels imposed by the two homogeneous members of the LS triad.
