Pressure effect on 6p-6s ir decay in xenon after two-photon excitation

Abstract

Pressure effects on the decay rates of the Xe 6p[ 1 2 ] 0 (0–800 mbar) and 6p[ 3 2 ] 2 (0–200 mbar) levels have been measured up to 6 × 10 8 s −1 using two-photon excitation. An analysis in terms of binary and ternary total quench rates for both transitions is presented. A radiative lifetime of 28.2 ± 0.5 ns has been found for both 6p[ 1 2 ] 0→6s[ 3 2 ] 0 1 (828.0 nm) and 6p[ 3 2 ] 2→6s[ 3 2 ] 0 2 (823.2) transitions.
