We investigate the limiting procedures to obtain Coulomb interactions from short-range potentials. The application of standard techniques used for the two-body case (exponential and sharp cutoff) to the three?body break?up problem is illustrated numerically by considering the Temkin-Poet (TP) model of e-H processes.
