J-matrix method of scattering for inverse-square singular potentials with supercritical coupling II. Regularization

This paper is a continuation of the previous one (Alhaidari et al., 2022). Here, we reformulate the same J-matrix theory by regularizing the inverse square singular potential. The objective is to restore rapid convergence of the calculation in the theory and recover the conventional tridiagonal representation. Partial success is achieved. (c) 2022 Elsevier Inc.
