· Phys. Rev. A; (United States)
The perturbed-stationary-state method, appended with electron translation factors, has been applied to charge transfer in Li/sup +/+Ca collisions for energies from 0.1 to 20 keV/amu. The Born-Oppenheimer wave functions and eigenvalues were generated using the pseudopotential technique, which reduced the many-electron system to a simpler two-electron problem. The molecular ground-state X /sup 1/..sigma../sup +/ is calculated to be bound and has the potential-well parameters R/sub e/ = 6.20a/sub 0/, D/sub e/ = 1.11 eV, ..omega../sub e/ = 235 cm/sup -1/, and B/sub e/ = 0.263 cm/sup -1/. From the scattering computations, a representative value for the charge-transfer cross section is 4 x 10/sup -15/ cm/sup 2/ at 5 keV/amu. The cross section decreases rapidly as the energy is reduced below 1 keV/amu. At all energies studied, the dominant electron-capture reaction product is the ground-state Li atom.
