Resonant anger spectra of Y, YF3 and YCl3 in Y LIII absorption edge

Abstract

Y LMM resonant Auger spectra of Y metal, YF3 and YCl3 around Y LIII absorption edge have been measured by means of monochromatized synchrotron radiation. Y Lα resonant x-ray emission spectra which are competitive process of Auger transition are also measured for Y metal and YF3. In Y metal, both spectra exhibit linear dependence with incident photon energy below the absorption threshold. Similar linear dependence is found in YF3 below and above the threshold. The results are interpreted as the resonant Raman process following core-electron excitation.
