Two-Photon Excitation of Cesium Alkali Metal Vapor 72D, 82D Kinetics and Spectroscopy

Abstract

Pulsed excitation on the two-photon Cs 62S 1/2 yields 72D3/2,5/2 transition results in time-resolved fluorescence at 697 nm and 672 nm. The rates for fine structure mixing between the 72D3/2,5/2 states have been measured for helium and argon rare gas collision partners. The mixing rates are very fast, 1.26 +/- 0.05 x 10 (-9) cm3=(atom sec) for He and 1.52 +/- 0.05 x 10(-10) cm3/(atom sec) for Ar, driven by the small energy splitting and large radial distribution for the valence electron.
