- W2018166013 abstract "Cette etude traite des phenomenes d'interactions entre un faisceau d'electrons et une cible, pour lesquels on utilise l'equation de transport de Boltzmann. On calcule la correction d'absorption f(χ), proportion de photons emergeant, en fonction de la longueur d'onde et de l'angle d'emergence a partir d'hypotheses effectuees sur la diffusion multiple. Les courbes representant le facteur d'absorption, tracees dans le cas ou une cible epaisse a ete bombardee par un faisceau d'electrons d'energie incidente comprise entre 10 et 60 keV, ont donne des expressions analytiqus compatibles avec les resultats deduits de diverses methodes de calcul des intensites × et de mesures experimentales.An electron transport equation is applied to study electron–specimen interaction in microanalysis. Values of the absorption function f(χ), the fraction of X-rays generated as a function of wavelength and take-off angle, are calculated. This expression is carried out with critical hypothesis on the multiple scattering process. Some curves are plotted in the case where a thick target is bombarded by an electron beam of an energy between 10 and 60 keV. Good agreement is found between this analytical calculation and several theorectical or experimental characteristic X-ray intensity determinations." @default.
