✦ Synopsis

SyncIzrotron radiation at LURE has been used to excite xenon in the pressure range of 50 to 200 ton. The subsequent second continuum fluorescence at 1720 A has been spectrally and temporally anz4yzed. The observed two-component decay of this emission. as well as various s0ectrd features. are si10wn to be in disagsement with some results previously re-po&d in the lite*t&e. _ 1 _ IJltrcducfion During the past few years, excitation and relaxation processes of xenon excimer states have been studied because of their application to high energy VUV Iaser development (see for e-ample refs. [ 1,2] and references therein)_ A recent conference on VTJV radiation physics 133 demonstrated that there is a great deal of interest in utilizing syncbrotron radiation (SR) from electron storage rings as a ContinuousIy variable source of monochromatic excitation in studies of xenon and other rare gases [4-l 11. By us'lng SR, the 'kinetics and interactions of the re&ting excited states can be examined without being disturbed by the ionic processes or electron effects [ 121 which are no&y present when high energy eIectrons, protons, or alpha particles are used_ In this letter, initial results (obtained at LURE utilizing the SR from AC03 are reported which deal with some spectral and kinetic properties of the 1720 A second continuum fluorescence of xenon. Excitation spectra were first obtained by detectin the total fluo-
