Symmetric charge transfer in low-energy ion-atom collisions. [Cross sections, below 1 keV, polarizability]

Journal Article · · Phys. Rev., A; (United States)
Previous calculations of ion-atom interactions by the pseudopotential and asymptotic methods are used in the computation of the cross section for symmetric charge transfer at energies below 1 keV. The results for Li/sup +/, Na/sup +/, K/sup +/, Rb/sup +/, Cs/sup +/, and Ca/sup +/ ions are compared with data obtained in beam experiments, and by optical-pumping techniques. The difference in the cross sections for /sup 2/P/sub 1///sub 2/ and /sup 2/P/sub 3///sub 2/ ions of Kr/sup +/ and Xe/sup +/ at thermal energies is studied, and the predictions are compared with recent mobility measurements. Cross sections are obtained for U/sup +/-U collisions, and the dependence of the thermal cross section on the polarizability is described. Symmetric charge transfer of the negative ions H/sup -/, Na/sup -/, and Cs/sup -/ is discussed briefly. (AIP)
