Abstract
The asymptotic model of exchange interactions for calculation of the polarizability of van der Waals complexes is discussed. The model is employed for description of the polarizability of interacting systems when their valence electron shells are weakly overlapped. The analytical expressions for the interaction polarizabilities that include induction, dispersion and exchange contributions have been obtained for X-Y and X-Y2 complexes. The calculation of the interaction polarizabilities of the complexes He-He, Ar-Ar, Kr-Xe, Xe-Xe, and Ar-H2 have been carried out.
