Abstract
The continuum distorted-wave eikonal-initial-state (CDW-EIS) theory of Crothersand McCann (Crothers D S F and McCann J F 1983 J. Phys. B: At. Mol. Phys.16 3229) used to describe ionization in ion–atom collisions is generalized (G)to GCDW-EIS, to incorporate the azimuthal angle dependence into thefinal-state wavefunction. This is accomplished by the analytic continuation ofhydrogenic-like wavefunctions from below to above threshold, using paraboliccoordinates and quantum numbers including magnetic quantum numbers, thusproviding a more complete set of states. At impact energies lower than 25 keVu−1, the total CDW-EIS ionization cross section falls off, with decreasingenergy, too quickly in comparison with experimental data by Crothers andMcCann. The idea behind and motivation for the GCDW-EIS model is toimprove the theory with respect to experiment, by including contributionsfrom non-zero magnetic quantum numbers. We also therefore incidentallyprovide a new derivation of the theory of continuum distorted waves forzero magnetic quantum numbers while simultaneously generalizing it.
