摘要:

By approximating the scattering potential in thelth partial wave equation with a series of constant segments, an exact solution in terms of spherical Bessel and Neumann functions becomes available. Continuity at the segment boundaries is achieved with the aid of a simple 2×2 matrix formalism and leads to exact expressions for the scattering phase shifts.
