Abstract
The near-K-edge x-ray photoabsorption spectrum of xenon was measured using synchrotron radiation. Several simultaneous two-electron excitation features were detected. Their identification is supported by nonrelativistic and relativistic energy-level calculations. The relative cross sections extracted from the data are consistent with previous measurements on Kr. Relativistic sudden-approximation-shake-theory cross sections are found to overestimate the measured ones by factors of 23, but closely follow level-dependent trends in the measured data.
