%X The authors investigate sodium-proton charge transfer using 14-state adiabatic, molecular-basis classical trajectory calculations in which a common translation factor and dynamical radial and rotational coupling terms are included. The differential cross sections are evaluated by the eikonal procedure from S-matrix elements obtained over 283 impact parameters at each energy. A fine mesh of energy and angle resolves new effects in scattering from a target excited by a circularly-polarized laser source. One of them is ascribed to velocity matching. Calculations were carried out on an Intel iPSC/2 parallel computer using a version of the EIKONXS package which is described.
