This shows that the lattice discretization technique could be a useful tool for the numerical solution of scattering problems in general. The approach is illustrated in the case of the Dirac delta function potential.7157-7163engArtigo10.1088/0305-4470/29/22/015WOS:A1996VW56400015Acesso restrito8031087349809439
