A time-dependent semiclassical lattice solution of the Schroedinger equation is used to calculate charge-transfer processes in proton collisions with lithium atoms. State-selective cross sections are obtained at 5-15 keV incident energy for laser excited 2p{sigma} states aligned parallel and 2p{pi} states aligned perpendicular to the ion beam. State-selective cross sections are also obtained at 5 keV for 1s{sup 2}2s ground states in which the polarization of a moderately intense pulsed laser is aligned parallel and perpendicular to the ion beam. The addition of a pulsed laser is found to have a strong effect on the charge-transfer cross sections to the n=3 excited states of hydrogen.
