A noniterative method, first communicated by Marriott, for solving the integro-differential equations which arise in electronatom scattering theory, is developed for a general class of nonlocal potentials for both coupled and uncoupled equations. Algorithms are given for the numerical solution in the uncoupled case using Simpson's rule for the quadrature scheme. As a sample calculation e/sup -/-He elastic scattering phase shifts are calculated using the static-exchange approximation with a renormalized density matrix. Hartree-Fock phase shifts are tabulated for He and Ne and compared to previous calculations. (auth)
