Separable-expansion method for potential scattering and the off-shell T matrix

T. K. Lim, Judith Giannini

Abstract

The closed-form, separable-expansion expression of Belyaev, Wrzecionko, and Irgaziev for the two-body $T$ matrix is studied numerically for the case of a Yukawa potential. The method shows good convergence for the elastic scattering amplitude at intermediate energies, yielding results almost identical to Glauber's eikonal method.
