Resonant charge transfer in slow Li~＋-Li（2s） collision

The resonant charge transfer process for Li＋-Li（2s） collision is investigated by the quantum-mechanical molecular orbital close-coupling（QMOCC） method and the two-center atomic-orbital close-coupling（AOCC） method in an energy range of 1.0 e V/u-104e V/u. Accurate molecular structure data and charge...

Description
Summary:The resonant charge transfer process for Li＋-Li（2s） collision is investigated by the quantum-mechanical molecular orbital close-coupling（QMOCC） method and the two-center atomic-orbital close-coupling（AOCC） method in an energy range of 1.0 e V/u-104e V/u. Accurate molecular structure data and charge transfer cross sections are given. Both the allelectron model（AEM） and one-electron model（OEM） are used in the QMOCC calculations, and the discrepancies between the two models are analyzed. The OEM calculation can also give a reliable prediction of the cross sections for energies below 1 ke V/u.
