✦ Synopsis

A high pressure microwave discharge source operating with a dilute mixture of Oa in Ne has been used to produce a supersonic nozzle beam of 0 atoms seeded in Ne. This low energy supersonic 0 atom beam has been used to study the reactive scattering of 0 atoms with Cla and CSa molecules at an initial translational energy E = 13 kJ mol-r. The results are compared with reactive scattering from the same reactions using a high energy 0 atom beam formed by seeding 0 atoms in He. The 0 i-Cl2 reaction proceeds via a short-lived collision complex where the lifetime of the collision complex depends upon the initial translational ener,T. However the 0 + CSa reaction follows a stripping mechanism which is unaffected by initial translational energy_
