摘要：

Classical Trajectory Monte-Carlo (CTMC) method has been used to investigate state selective electron capture by He2+ ions colliding with Li(2s) and Li*(2p) in Sigma as well as Pi alignments in the energy range 1-15 keV/amu. He+(4l) electron capture, line emission [He II(n = 4 --> 3)] cross-sections and alignment parameters have been calculated and analyzed in the light of the available results. The undulatory structure of the capture and emission cross-sections have been explained qualitatively in terms of a quasimolecular ion formation. Projectile impact energy and spatial overlap play crucial role in determining the alignment effects.
