Long-range interaction effects in a formation of dipole-bound anions induced by collisions of Rydberg atoms with polar molecules

Abstract

We report results of theoretical studies of dipole-bound anion formation reactions in collisions of polar molecules CH3NO2,CH3CN, and C3H4O3 with Rydberg atoms Cs(ns),Xe(nf), and Rb(nl) (l=0, 3, and n−1). It is shown that the inclusion of the long-range interaction effects into the calculations of the Rydberg-covalent–ionic coupling terms is crucial for a reliable quantitative description of such processes. A particular attention is paid to the comparison of the results obtained with the calculations performed using previous models and with the experiment.
