Title: Cross sections for electron capture in H{sup +}-Li(2p{sigma},{pi}{sup {+-}}) collisions

Abstract

State-selective and total single-electron-capture cross sections in collisions of H{sup +} with the excited Li{sup *}(2p) atom have been investigated by using the full quantum-mechanical molecular orbital close-coupling (QMOCC) method in the energy range 0.001-3 keV/u and by the two-center atomic orbital close-coupling (TC-AOCC) method in the energy range 0.1-100 keV/u. The present results are also compared with data from other sources when available. It is found that the total and partial electron-capture cross sections are sensitive to the initial p-state charge cloud alignment, particularly in the low-energy region.
