Very high resolution electron spectroscopy with third generation synchrotron radiation sources: the resonant Auger decay spectrum of the Xe 4d5/2−16p state

Abstract

We have recorded an Auger decay spectrum of the resonantly excited Xe 4d5/2−16p state between 36.4 and 37.3 eV kinetic energy. The spectrum was obtained under resonant Raman conditions, with a bandwidth of ≈6 meV for the exciting radiation, much smaller than the natural lifetime width of 110–120 meV. The full width at half maximum of the peaks in the spectrum was 10 meV, making it possible to completely resolve structure that overlapped in earlier studies.
