Tests of anL2Discretization Procedure for Approximating Three-Body Breakup Effects

Abstract
The accuracy of an L2 discretization approximation as a means of incorporating effects of three-particle breakup on two-body scattering amplitudes has been tested in a soluble three-particle model. The coupled-reaction-channel Ansatz for the Schrödinger wave function was found to respond better to discretization than any of the connected-kernel, three-particle scattering formalisms.
