Electron-Alkali-Atom Scattering—A Nonadiabatic Approach

Abstract

The nonadiabatic method of Temkin which has been applied to electron-hydrogen scattering is generalized to the problem of electron-alkali scattering. A two-body equation is derived in which the core of the atom has the principal effect of modifying the two-body interaction and of excluding the two extra-core electrons from the occupied states of the core. This equation may be viewed as a generalization of the Bethe-Goldstone equation for the problem of scattering from a finite system.
