EXCITATION-FUNCTIONS OF CATION FORMATION IN COLLISIONS OF DIATOMIC-MOLECULES WITH AN IONIC BOND - CSCL+RBI

The excitation functions for the formation of cations Cs+, Rb+, CsRbCl + and CsRbI+ in collisions of alkali-metal halide molecules CsCl and R bI have been measured in crossed molecular beams for the collision ene rgy ranging from 3 to 10 eV. Trajectory simulation of dissociative pro cesses in the CsCl + RbI system has been performed on a potential-ener gy surface chosen to be the sum of six pairwise interaction potentials . The calculated excitation functions agree well with the experimental data. Simulation of the CsCl + RbI reaction by a hard-sphere model ha s also been carried out.
