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( 3 P 2 ), 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. |
