Charge-transfer cross sections from the ground state of atomic hydrogen into the final 1s, 2s, 2p, 3s, 3p, and 3d excited states of the Li/sup 2 +/ ion by the impact of fully stripped lithium ions are calculated in the Coulomb-Born and Born approximations. The results for the total charge-transfer cross sections are compared with the existing experimental findings and other theoretical calculations. The present calculated results obtained by the Coulomb-Born approximation are found to be in excellent agreement with the experimental results throughout the energy region considered, except in the low-energy region E<275 keV, whereas the present Born results grossly overestimate the experimental findings. The existing theoretical results obtained for the unitarized-distorted-wave approximation or obtained by the Monte Carlo approach are in better agreement with the observed values in the low-energy region, as compared with the present Coulomb-Born or Born results. However, with an increase of the incident-ion energy, the earlier calculated results show poor agreement with the observed values.
