The dynamical radial and rotational coupling terms and a common translation factor (CTF) are included. The effect of the choice of the coordinate centre on the total charge exchange cross sections to H( n = 2) is clearly demonstrated when no CTF is included. The alignment dependence of the capture to H(n =2) is obtained and is satisfactorily compared with the atomic expansion calculations. State-to-state charge exchange differential cross sections are calculated; the alignment and orientation effects are expected to be observable at the collision energy 0.5 keV where they are spread out at scattering angles .Q> 0.1".C.

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. J. AllanC.
