The Coulomb-projected Born approximation has been used to calculate the total charge-transfer cross sections for ..cap alpha.. particles (He/sup 2 +/) colliding with hydrogenic systems at medium and high energies. The present results overestimate the recent experimental data of Hvelplund et al. for the system He/sup 2 +/+H in the energy range 0.5 to 5 MeV. Further, it is seen that the present scaled results (Z/sup 6//sub T/sigma) for capture into the n = 1 state follow the universal curve in the energy range E/Z/sup 2//sub T/> or =100 keV when plotted against E/Z/sup 2//sub T/ and are in agreement with the scaling formula of Nikolaev.
