Effectiveness of the product stabilization in direct three-body recombination

The optimal kinematic parameters for the formation of the most stabilized products in direct three-body recombination Cs + Br + R → CsBr + R with R = Hg, Xe, Kr are determined by the deformed polyhedron method for the third body energy and the ion encounter energy ranging from 1 to 10 eV. The stabilization effectivity functions are obtained for each atom, and the mean effectivities of the atoms in the formation of products with the lowest internal energy are calculated. The Xe and Hg atoms are almost equally effective in energy removal from the recombining pair due to high hardness of the repulsion potentials in the interactions of these atoms with the ions. The Kr atom effectivity is much less because of much softer repulsion in the corresponding pairwise interactions. The dynamical mechanism of the third body collisions with the ions affects greatly the energy transfer effectiveness.
