Charge transfer cross sections for Li/sup 3 +/ + H, Be/sup 4 +/ + H, B/sup 5 +/ + H, and C/sup 6 +/ + H collisions are calculated for ion-impact energies from 0.025 to 200, or to 2000 (for the C/sup 6 +/ + H case) keV/amu by means of the previously proposed unitarized formula based on the distorted-wave Born approximation. The results, compared with other theoretical and experimental values, show that the present formula is very useful for impact energies from 2 to 100 keV/amu, but tends to overestimate cross sections for impact energies greater than 100 keV/amu. It is suggested that the formula can be improved by taking direct-excitation and ionization channels into consideration. A scaling rule based on the cross section obtained by means of the present method is also considered, and is applied to scaling of the experimental data.
