Calculations are presented of cross sections for electron capture from atomic hydrogen to n, l excited states of p/sup +/, ..cap alpha../sup + +/, and Be/sup +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/sup +8/ in the BK approximation. Capture occurs into levels with increasing n and l as the projectile charge Z/sub 1/ is increased. While the BK and JS ratios sigma/sub n/l/..sigma../sub n/,l sigma/sub n/l are quite similar for p + H, these two approximations give rather different distributions in n and l for Be/sup +4/ where transfer to excited levels dominates.
