Time Resolved Spectroscopy of Krypton and Xenon Molecules Excited by Electron Impact and by Monochromatic Synchrotron Radiation.
Abstract
The dependence of the fluorescence from molecular states of krypton and xenon measured following pulsed excitation of dense pure gas samples or binary gas mixtures by a low intensity beam of high energy electrons or by monochromatized vacuum ultraviolet (VUV) synchrotron radiation. The selectivity of the initial states excited by monochromatic photons is a significant advantage over electron beam excitation for the determination of radiative lifetimes and rates for reactions involving the lowest 1(u) and O(u)+ states of krypton and xenon. Electron beam excitation remains valuable for study of excited states which cannot be reached by photoexcitation, particularly the ionic states of the rare gases.
