ELECTRON-TRANSFER IN KEV LI-NA-ASTERISK(3P) COLLISIONS .2. MOLECULAR-BASIS MODEL()

The velocity dependence of state-to-state integral cross sections for electron transfer and excitation in Li+-Na(3s, 3p) collisions is studi ed in the 0.05-0.3 an velocity range using the impact parameter semicl assical method and a 28-state molecular orbital basis model including a common translation factor. The initial orbital alignment dependence of electron transfer is in fair agreement with recent experiments and with atomic orbital model calculations. The main electron transfer cha nnel from Na(3p) is to the Li*(2p) states. The integral cross section s from an aligned or oriented Na(3p) state to an aligned or oriented Li(2p) state and vice versa and the corresponding alignment and orien tation parameters are presented as a function of the impact velocity.
