Kinetic studies following state-selective laser excitation
Measurements of state-to-state deactivation cross sections and radiative lifetimes were made for Xe*(6p,6p[prime],7p) and Kr*(5p) states in xenon and krypton buffer gases. These results are relevant to kinetic models of both excimer lasers and the infrared xenon laser. Attempts were made to continue studies of two-photon laser assisted collisions in the reaction Xe + Cl[sub 2] + [Dirac h][omega] [yields] (Xe[sup +][circ]Cl[sub 2][minus]) [yields] XeCl*(high v) + Cl. These experiments along with studies of the XeCl*(B, C, and D) branching fractions are reported along with studies of the two-photon spectroscopy of Cl[sub 2]. In addition, significant progress was made in the study of the spectroscopy of small molecules and excimers formed in supersonic beams. Although emphasis is on xenon excimers excited in two-photon transitions, larger rare gas clusters were measured splitting between the 2s and 2p excitons is not explainable by currently excepted models for excitons in liquid xenon. Finally, work to obtain fluorescent spectra of xenon excimers in supersonic jets is described.
