ON THE INTERACTION POTENTIALS FOR THE ELECTRONIC-ENERGY TRANSFER-REACTIONS XE(P-30,2)+N2(X)-]XE(S-10)+N2(B3PIG)

An analytical description of the interaction potentials of the title reactions is given. Based on an earlier, essentially repulsive model, it incorporates (a) for both entrance channels, ion-induced dipole contributions; (b) for Xe(3P2), the splitting into three branches corresponding to the different electronic angular momentum projections; (c) for the exit channels, slight modifications of the van der Waals potential wells. The calculated characteristics of the entrance/exit potential crossings of this improved model explain qualitatively all important details of the observed product vibrational/rotational/fine structure distributions, including the exothermic channels not amenable to the previous description. © 1990.
