Long-range features of the F-HBr and F-HI potential energy surfaces from crossed molecular-beam experiments: a model analysis

Abstract

Relative differential and integral cross sections for scattering of fluorine atoms by hydrogen bromide and hydrogen iodide have been measured at collision energies from 5 to 175 meV. Treating the experimental data in terms of a single potential of the Lennard-Jones type, we have evaluated the well depths and equilibrium distances of the long-range interaction potentials.
