Crossed Molecular Beam Reactions of Tritium Bromide

Abstract

A radioisotope detection method was successfully employed to determine the product distribution in crossed molecular beam experiments. Angular distributions of the atomic tritium product were measured for the reactions K+TBr→KBr+T and Cs+TBr→CsBr+T. The measured distributions correspond to ``backward'' scattering (χ≃π) of the potassium bromide relative to incoming potassium in the center‐of‐mass coordinate system for both reactions, i.e., the reactions are rebound reactions.
