Inner-shell corrections to proton stopping power for low-Z atoms are often taken from hydrogenic calculations. To check the relevance of the hydrogenic correction, I have analyzed explicit Born-approximation stopping-power calculations for Al ions (Al/sup n/+, 1< or =n< or =11) to extract the inner-shell corrections. I find a significant variation in inner-shell corrections with degree of ionization. For the K shell of Al ions the hydrogenic correction is within a factor of 2 of the corrections from the explicit ion results between 1 and 10 MeV. In the analysis of the explicit calculations, a remarkable constancy is found in the inner-subshell I/sub n/l values, as the degree of ionization is varied.
