Energy Dependent Stereodynamics of the Ne(3P2) + Ar Reaction

The stereodynamics of the Ne(P-3(2)) + Ar Penning and associative ionization reactions have been studied using a crossed molecular beam apparatus. The experiment uses a curved magnetic hexapole to polarize the Ne(P-3(2)), which is then oriented with a shaped magnetic field in the region where it intersects with a beam of Ard (S-1). The ratios of Penning to associative ionization were recorded over a range of collision energies from 320 to 500 cm(-1) and the data were used to obtain Omega state dependent reactivities for the two reaction channels. These reactivities were found to compare favorably to those predicted in the theoretical work of Brumer et al.
