Auger electron spectra of Kr2p holes using monochromatic soft X-rays

Normal Auger electron spectra from Kr2p hole states, L23M45M45 and L23M23M45, have been measured using monochromatized synchrotron radiation and a high resolution electron spectrometer. Measured spectra were reproduced with a fitting calculation, where Voigt functions including an instrumental resolution and natural lifetime widths of related core hole states were used. At most final states estimated energies for spectral peaks agree with those by electron and ion beam techniques. Relative intensities for some peaks are appreciably different from the previous results.
