Abstract
We present a variation iteration procedure for nonreactive multichannel scattering processes. Its essential features include the expansion of the trial function in terms of the eigenfunctions of a zeroth-order Hamiltonian; the use of the zeroth-order Green's function to impose the correct outgoing behavior on the trial function; and further improvement of the transition matrix element by iteration. The procedure is applied to a problem in atomic-molecular energy exchange.
