Alignment and orientation in Li(2pm)–H+ charge-transfer collisions

Abstract

Initial orbital alignment and orientation effects, have been studied in slow (0.2–10 keV) quasi-resonant charge-transfer collisions of laser-excited Li*(2p) atoms with H⁺ ions. The standard semi-classical impact parameter method with a common translation factor has been employed using an adiabatic molecular basis. Pronounced alignment effects for the transition to H*(n= 2) were found to be a function of collision energy but orientation preferences from Li*(2p_–1) were obtained over the entire energy range.
