Resonant charge transfer in alkali-ion--alkali-atom collisions is investigated by using the molecular-orbital expansion method incorporating the use of electron translation factors. Molecular wave functions and eigenenergies are obtained by the pseudopotential method. Molecular properties, R/sub e/, D/sub e/, and ..omega../sub e/, obtained in the present calculation are in good accord with other recent theoretical results, as well as spectroscopic measurements. Three-state close-coupling calculations reproduce the positions of the maxima and minima in the oscillatory structure seen experimentally in the resonant-charge-transfer cross sections for the Li/sub 2/ /sup +/ and Cs/sub 2/ /sup +/ systems. The magnitude of the total cross sections and their velocity dependence are in agreement with experimental measurements.
