A modified linear algebraic approach to electron scattering using cubic splines

A modified linear algebraic approach to the solution of the Schrodiner equation for low-energy electron scattering is presented. The method uses a piecewise cubic-spline approximation of the wavefunction. Results in the static-potential and the static-exchange approximations for e-+H s-wave scattering are compared with unmodified linear algebraic and variational linear algebraic methods. (author)
