摘要：
The effect of the velocity of the incident ions in the nl-distributions of the electron capture in collisions of highly charged Ar8+ ions with a lithium target is studied. These Ar8+-Li(2s) collisions are experimentally studied by means of near UV and visible photon spectroscopy (200-600 nm) in the 1.5-4.5 keV amu(-1) energy range and theoretically analysed by means of the three-body classical trajectory Monte-Carlo method. The presence of projectile core-electrons strongly affects the population and collision energy dependence of low l values produced in the electron capture reaction. It is shown that the sigma(nl) partial cross sections (n = 8, 9 and l = 0, 1, 2) increase with decreasing energies.
