X-ray laser photopumped resonance fluorescence
Résumé
A calculation of the resonance fluorescence spectrum of the 146.526 Angstrom 3d-2p transition of fluorine-like magnesium photopumped by the 146.515 Angstrom zirconium X-ray laser line is discussed in connection with an experimental measurement in a hot, dense laser produced plasma. The calculation of the fluorescence spectral profile is based on a recent extension of the Frequency Fluctuation Model (FFM) that enables the computation of radiative redistribution and other higher order radiative processes. The discussion of the photopumping experiment includes an analysis of the optimal plasma conditions and the associated characteristics of the redistributed radiation with specific reference to the experimental feasibility. The potential information to je acquired in the comparison of the computational and experimental results also will be considered. (C) 1997 Published by Elsevier Science Ltd. All rights reserved.
