✦ Synopsis

TWO series of transitions invotving excitation of the Sd *Dsa excited state of Cs, np zPan * Sd *Ds~ (n = J J -16) and& 2: -_ Sd 'Ds~ (n = 8-14). have been obyved as a fluorescence excitation spectrum in Cs-rare gas mixtures using a N2 Iaser pumped dye laser. The population of the Sd *D 5n level of Cs is exptained as a laser excitation during a Cs-rare gas collision.

1. introduction

During the course of another investigation of ff uorescence excitation spectra df Cs vapor with a N2 laser pumped dye laser, the purpose of which is irrefevant in the present context, a new fluorescence excitation line at 15445.4 cm-l was observed on the addition of a few torr of Ar, By comparison with the energy level table for the Cs atom [ 11, it appeared
