Resonance Auger spectra of free Rb atoms

Resonance Auger electron spectra of atomic Rb are studied both experimentally and theoretically. 3$d_{5/2}$ electrons were excited selectively by the monochromated synchrotron radiation to 5p orbitals, and the spectrum of the ejected electrons was measured in the kinetic energy range of 7–95 eV. The experimental spectrum is compared with the calculated theoretical profile. For comparison the normal 3d Auger spectrum was also measured using electron-impact excitation.
