Generation and kinetic studies of Xe(5d[3/2]{sub 1}) resonance state atoms
Two-photon, pulsed-laser excitation of the Xe(4f[3/2]{sub 2}) level with concomitant amplified stimulated emission has been used to prepare the Xe(5d[3/2]{sub 1}) resonance state atoms in a few Torr of Xe. Observation of the vacuum ultraviolet emission at 119.2 nm from the Xe(5d[3/2]{sub 1}{r{underscore}arrow}5p{sup 6} {sup 1}S{sub 0}) transition permits direct monitoring of the decay rate of the concentration of the Xe(5d[3.2]{sub 1}) atoms, and the bimolecular quenching rate constants were measured at room temperature for Ar, Xe, CF{sub 4}, H{sub 2}, N{sub 2}, CO, CH{sub 4} CC;{sub 4}. and C;{sub 2}. The decay rate in Ne was too slow to measure and the decay mechanism in Kr was complex. The magnitudes of the quenching constants for Xe(5d[3/2]{sub 1}) atoms by molecules resemble those for the Xe(6s'[1/2]{sub 1}) and Xe(6p[1/2]{sub 0} or [3/2]{sub 2}) states. In addition to introducing a slow quenching rate of the Xe(5d[3/2]{sub 1}) atoms, the addition of Ar to the cell containing a few Torr of Xe seemed to enhance the 119.2 nm emission intensity.
