p { margin-bottom: 0.21cm; } State selective charge exchange cross sections and momentum spectra are calculated for collisions of Xe18+, Xe24+ and Xe54+ ions with Na(3s) and Na*(3p) over the energy range of 0.1 to 10.0 keV/amu. The CTMC method is used which includes all two-body interactions. The n-level cross sections are found to be rather insensitive to collision energy below 1 keV/amu. In contrast, the transverse momentum cross sections for specific n-levels change rapidly with energy. However, this latter variation in energy is found to be in general agreement with simple scaling rules. Experimental state-selective data are available for Xe18+ and Xe24+ over a limited energy range; they are found to be in reasonable accord with the calculations.
