Electron capture into arbitrary n,l levels of fast projectiles
The approach to electron capture previously developed by the authors is extended to describe the capture of hydrogenic 1s electrons into arbitrary hydrogenic n,l excited states of fast projectiles. A simple formula for n,l distributions is derived. Capture occurs mainly into states around n/sub res/approx. =Z/sub p//Z/sub t/ (Z/sub t/ and Z/sub p/ are the target and projectile charges) and lapprox. =n/sub res/-1. The n,l distributions for O/sup 8 +/+H (1s) ..-->..O/sup 7 +/(nl)+H/sup +/ and for O/sup 8 +/+He(1s/sup 2/) ..-->..O/sup 7 +/(nl)+He/sup +/(1s) are graphically displayed as representative examples. For the reactions H/sup +/+H(1s) ..-->..H(nl)+H/sup +/ and H/sup +/+He(1s/sup 2/) ..-->..H(nl)+He/sup +/(1s) (nl=2s,2p,3s,3p,3d, and 4s), good agreement is obtained with experimental cross sections.
