A reduced coupling matrix-element formula has been developed for application to the class of reactions A/sup +//subz/ + B ..-->.. A/sup +//subz/ /sup -/ /sup 1/ + B/sup +/, where 4 < or = z < or = 54. The reduced coupling matrix elements have been combined with an absorbing-sphere model based on the Landau-Zener method to obtain a relatively simple formalism for obtaining the electron transfer total cross sections. The method assumes a large number of final product channels available for reaction and is applicable for relative velocities v/sub rel/ < or = 1 x 10/sup 8/ cm/sec. For such electron transfer reactions, the cross sections at a given velocity are dependent primarily on the charge state of the incident ion and the ionization potential of the target atom; also, for a given colliding pair, the cross section is found to be almost independent of the relative velocity. Cross sections have been calculated for H, He, Ne, Ar, Kr, Xe, and H/sub 2/ targets. For the cases of H/sub 2/ and Ar there are experimental data available; the comparison between theory and experiment is quite favorable. (AIP)
