ELECTRON-CAPTURE FROM ATOMIC-HYDROGEN INTO EXCITED N,L LEVELS OF PROJECTILES WITH Z1 GREATER-THAN-OR-EQUAL-TO 1

Calculations are presented of cross sections for electron capture from atomic hydrogen to n, l excited states of p+, ++, and Be+4 at velocities of about 100 keV/amu using both the Brinkman-Kramers (BK) and Jackson-Schiff (JS) approximations, and to excited states of O+8 in the BK approximation. Capture occurs into levels with increasing n and l as the projectile charge Z1 is increased. While the BK and JS ratios nln,l nl are quite similar for p+H, these two approximations give rather different distributions in n and l for Be+4 where transfer to excited levels dominates. © 1978 The American Physical Society.
