Abstract
We use Feshbach's projection formalism to write an equation for the wave function that describes the relative distance between the centers of mass of the two ions. We assume that the Q-space can be truncated at the excitation of 1p-1h in either one or the other ion, leaving one of them in its ground state. In the propagator of the effective potential, the two-body interaction is replaced by the ion-ion mean field VMF. The matrix elements of the elementary interaction are of finite range, represented by an effective Wigner force. The total many-body wave function is antisymmetrized only in the partial intrinsic wave function of each ion. Calculations are done in the Thomas Fermi approximation. The Coulomb energy is not considered.
