- W3124221335 abstract "Two developments in scattering theory are reported. We show, in a practical way, how one can calculate the scattering amplitude without invoking a partial-wave expansion. First, the integral expression for the scattering amplitude $f(ensuremath{theta})$ is simplified by an analytic integration over the azimuthal angle. Second, the full scattering wave function that appears in the integral expression for $f(ensuremath{theta})$ is obtained by solving the Schrodinger equation with the finite element method. As an example, we calculate electron scattering from static hydrogen (the Hartree potential). With minimal computational effort, we obtain accurate and stable results for the scattering amplitude." @default.
