Abstract
A direct method to derive the expression for the polarization potential between a charged particle and a two-fragment quantum system is developed. This method is based on the asymptotic properties of the two-body Coulomb Green function. The explicit form of the polarization potential constant is obtained for low-energy deuteron-nucleus scattering and for ion-hydrogen scattering. The properties of the polarization potential at high collision energies are applied to obtain an expression for the ion-atom scattering total cross section.
