Investigation of the vacuum ultraviolet fluorescence of gaseous xenon under optical excitation in an extended wavelength region

Comparative study of the formation and decay of xenon excimers following selective excitation of the 5p56s states: spectroscopic and kinetic analysis

“…This study was formerly carried out by several authors, using either the synchrotron radiation [19,21] or simultaneous absorption of three photons [22]. Here, a few measurements of the luminescence of the second continuum, following excitation of the dissociative 1 g ( 3 P 1 ) state, were performed just to verify the consistency of our results with those already obtained for the first continuum, at the same excitation wavelength.…”

“…The temporal analysis of the first continuum showed the formation of excimers from the metastable atomic state, whereas only the 3 P 1 resonant state was excited initially. Such a transfer has already been considered by Brodmann and Zimmerer [19] and Salamero et al [22] and corresponds to reaction (R-9) of the kinetic scheme. The dissociative state thus formed could be one of the 2 u , 2 g , 1 g or 0 − g states.…”

“…The first was the understanding of the excimer structure either by ab initio calculations [7,8] or from spectroscopic data [9][10][11][12]. The second was the study of the reactional processes as well as the determination of lifetimes and rate constants: initially done by performing excitation with particles [13][14][15] or with discharges [16][17][18], and then well developed using either synchrotron radiation [19][20][21] or multiphotonic absorption by means of a laser [22][23][24][25].…”

Dielectric screening--, multiple scattering--, and quantum indistinguishability effects in the IR emission spectrum of Xe$_2$ excimers in dense Xe gas

“…Xenon is the most accurately studied gas because of its ability to efficiently convert the excitation energy in intense VUV radiation [4]. Upon excitation accomplished by using several techniques, including highenergy particles [5,6,7,8,9,10], electrical discharges [11,12,13], multiphotonic absorption by means of a laser [2,14,15,16,17,18,19,20,21], and synchrotron radiation [14,22,23,24], three-body collisions of excited and ground-state atoms lead to the formation of excited dimers whose decay toward the dissociative ground state yields the 1st and 2nd VUV continua at approximately 150 and 170 nm.…”

Infrared emission spectrum and potentials of 0+uand 0+gstates of Xe2excimers produced by electron impact

“…Nearly all of the investigations on Xe excimers aim at explaining the processes leading to the emission of the VUV 1st-and 2nd continuum observed under different experimental conditions in gas excited by discharges [4], UV photons [5,6], multiphotons [7,8], or high-energy particles [9,10,11,12].…”
