Total and partial cross sections for charge transfer in collisions of multicharged ions with atomic hydrogen

Journal Article · · Phys. Rev., A; (United States)
;
The total cross sections for charge transfer in Ne/sup 10 +/+H, Si/sup 14 +/+H, and Ca/sup 20 +/+H collisions are calculated for ion impact energies of 0.025--2000, 0.025--5000, and 0.1--10 keV/amu, respectively, by means of a unitarized-distorted-wave-approximation method. A scaling rule is derived from the results to predict cross section data. The partial cross sections for electron transfer into the individual orbitals around the projectiles are also investigated. The results show that the most probable principal quantum number of the final state is almost independent to impact energy below 100 keV/amu, while with increasing impact energy above 100 keV/amu it decreases considerably. The strong effects of level crossing and momentum transfer are confirmed to appear in the distributions of final-state population over angular momentum quantum number.
