The Existence Regions for Direct Three-Body Recombination of Cesium and Bromide Ions in the Presence of Krypton, Xenon, and Mercury Atoms.

Within the framework of the quasiclassical trajectory method on semiempirical diabatic potential energy surfaces, we have considered the existence regions for direct three-body recombination Cs⁺ + Br^– + R → CsBr + R (R = Kr, Xe, Hg) in the case where the encounters of the Cs⁺ and Br^– ions are central and the delay parameter vanishes. The recombination regions are determined using a much more precise procedure than in the previous works. Particular attention is paid to the recombination opacity functions and to the role of the orientation angles in the outcome of a three-body collision. The performed calculations demonstrate a great complexity of the structure of the recombination regions. [ABSTRACT FROM AUTHOR]
