Collisional deactivation of two-photon laser excited xenon 5<i>p</i>5 6<i>p</i>. I. State-to-state reaction rates

Abstract

Laser-induced fluorescence of two-photon excited Xe 5p5 6p is analyzed to obtain collisional branching fractions and state-to-state reaction rates. The intramultiplet quenching is found to be described surprisingly well by a simple statistical model. Based on the molecular potentials involved, curve crossing mechanisms are discussed.
