Scattering solutions of the spinless Salpeter equation

A method to compute the scattering solutions of a spinless Salpeter equatio n (or a Schrodinger equation) with a central interaction is presented. This method relies on the three-dimensional Fourier grid Hamiltonian method use d to compute bound states, it requires only the evaluation of the potential at equally spaced grid points and yields the radial part of the scattering solution at the same grid points. It can be easily extended to the case of coupled channel equations and to the case of nonlocal interactions. [S1063 -651X(99)02701-4].
