The bond energies of the four cesium halides are determined from the threshold for collision-induced dissociation to ion pairs by rare gas atoms. The bond energies (to neutral atoms) are 5.32 +/- 0.08, 4.58 +/- 0.08, 4.00 +/- 0.08, and 3.47 +/- 0.15 eV for CsF, CsCl, CsBr, and CsI, respectively. Except for CsI the ion thresholds are obtained from the sharply peaked cross section vs. energy curves for CsM/sup +/ + X/sup -/ formation (M = rare gas atom; X/sup -/ = halide ion) and for CsI the ion threshold is obtained from the onset of the channel M + Cs/sup +/ + I/sup -/. Comparison is made with bond energies determined by other techniques as well as that derived from the T-Rittner model potential.
