RESEARCH ON METASTABLE SPECIES IN ATOMIC AND MOLECULAR BEAMS PRODUCED BY CHARGE TRANSFER. TASKS 1, 2, AND 3
Abstract
Near-resonant electron capture reactions are being used to produce beams of long-lived excited atoms and molecules (metastables) suitable for studies of important collision processes of such species. The research has progressed sufficiently to allow the measurement of cross sections as a function of kinetic energy for metastable deactivation processes. Reactions in which the deactivation was dominated by Penning ionization or by symmetric energy transfer were chosen for study so that cross sections for these particular processes could be obtained. Studies of the optical radiation emitted from states excited by electron capture collisions have also provided useful results. Measurements of the gas phase quenching and reactions of O((1)D) by O2, N2O, CO, CO2, and H2 are nearing completion. The excitation and de-excitation of O2(b(1)Sigma+), N2(A(3)Sigma+u), and O((1)S) in a weak discharge are being successfully studied.
