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. %R 10.1088/0953-4075/23/16/007 %J Journal of Physics B: Atomic, Molecular and Optical Physics %L upm61154 %V 23 %D 1990 %A R.
