Abstract
Li(n = 2) to H*(n = 2,3) and Li*(2p, n = 3) charge transferand excitation processes are studied in the medium-energy range0.1-10 keV. The static model includes a basis of 26 molecularstates. The lithium atom is described using a model potentialand the semiclassical impact parameter method with straighttrajectories is used for the dynamical simulation. A commontranslation factor is included to account correctly for theelectron translation movement.For this collision system, we calculate the total cross sectionsand probabilities for the different capture and excitationprocesses. The calculation reflects a Lyα radiationenhancement for the capture to H*(2p) from Li*(2p). Astrong alignment effect in the capture processes to H*(2)is also shown and evaluated through the alignment parameterA(n = 2,3). Finally, we provide a mechanism through thenon-adiabatic radial and rotational couplings, showing theimportance of the H*(3) and Li*(3) states in thiscollision.
