Abstract

The nonradiative charge-transfer processes of Li++Na(3s) collisions have been investigated by using the fully quantum-mechanical molecular-orbital close-coupling method and the two-center atomic-orbital close-coupling method for the energy range of 10-4-2keV/u and 0.2-10keV/u, respectively. The radiative charge-transfer, radiative decay, and radiative-association processes have been studied by employing the fully quantum, optical-potential, and semiclassical methods for the energy range of 2×10-10-110eV/u. The nonradiative charge-transfer processes dominate the collisions for energies above 0.2 eV/u while radiative decay processes dominate in the lower-energy region. Especially, we found that the radiative-association process is more important than the radiative charge-transfer process when E<2×10-2eV/u. The rate coefficients of nonradiative and radiative processes are also given for the temperature range of 3×104-2×109K and 10-6-10³K, respectively. [ABSTRACT FROM AUTHOR]
