We present total charge exchange cross sections for collisions of Li(1s22s2S) with H(1s) in presence of a linear polarized laser field of intensity 0.05 ≤ I ≤ 1 TW/cm2 and wavelength 5 103 ≤ λ ≤ 14 103 Å. Our calculation shows that the laser field can increase the cross section of this reaction by a factor of ten at impact energies E < 0.1 ke V/a.m.u. The mechanism of this process is discussed and it is shown that both atomic and molecular radiative transitions can take place depending on the laser wavelength employed.
