摘要：

The J-matrix method was developed to handle regular short-range scattering potentials. Its accuracy, stability, and convergence properties compare favorably with other successful scattering methods. Recently, we extended the method to the treatment of potentials with r(-1) singularity. In this work, we do the same for r(-2) singular potentials.
