In this paper, the approximate amplitude formula of the preamble formal function is modified by the effective potential of Li atomic valence electron. The approximation method of effective potential correction procedure is proposed and the total electron capture cross section in the collision of H + and He2 + with Li atom is calculated. Obtained and experimental results are in good agreement.
