Polarization dependence of resonant charge transfer in low-energy collisions of Na/sup +/ with laser-excited Na/sup /(3p)

Journal Article · · Phys. Rev. Lett.; (United States)

Relative differential cross sections for charge-transfer scattering have been measured over the collision energy range E/sub c.m./ = 45--75 eV. With linearly polarized light exciting Na(3s) to Na((3p) the dependence of the charge-transfer cross section on the predominant preparation of the ..sigma.. or Pi excited states of the ionic quasimolecule Na/sub 2//sup +/ has been studied. The results are compared to simple model calculations. It is found that the resonant charge exchange is most probable for the predominant preparation of the Na/sub 2//sup +/(2..sigma../sub g,u/) excited states.
