THEORETICAL LIFETIMES, TRANSITION RATES, X-RAY WAVELENGTHS, AND FLUORESCENCE YIELDS OF HOLLOW NEON ATOMS WITH DOUBLE K-SHELL VACANCIES

Abstract

X-ray and Auger transition rates, X-ray wavelengths, lifetimes, and fluorescence yields have been calculated for multiply-stripped hollow neon atoms (Ne q+ , q=2–8) with double K-shell vacancies. The calculations have been performed in the intermediate coupling scheme using Hartree–Fock atomic model. The line fluorescence yields are found to decrease as electron population in the outer L shell increases. We have found large discrepancies between configuration-average fluorescence yields calculated from the configuration-average X-ray and Auger rates, often used to interpret experimental ion–surface and ion–atom collision data, and those calculated from the line fluorescence yields.
