- Abstract
A method for calculating the complex optical potential of slowly colliding Rydberg atom A** and neutral atom B in the ground electronic state is suggested. The method is based on the asymptotic approach and the theory of multichannel quantum defects, which uses the formalism of renormalized Lippmann–Schwinger equations. The potential is introduced as the <q|V[sub opt]|q> matrix element of the optical interaction operator, for which the integral equation is derived, and is calculated in the basis set of free particle wave functions |q>. Fairly simple equations for the shift and broadening of the ionic term are obtained, and the principal characteristics of these equations are analyzed. By way of illustration, the optical potential of the Na**(nl) + B systems, where B is a rare gas atom, is calculated. © 2002 MAIK “Nauka / Interperiodica”.
