Precision measurements of<i>K</i>and<i>L</i>transitions in xenon: Experiment and theory for the<i>K</i>,<i>L</i>, and<i>M</i>levels

Abstract

Wavelengths of xenon L-series x-ray lines were measured with high accuracy using a double flat-crystal vacuum spectrometer. Wavelengths of the more prominent xenon K-series lines which had been obtained previously are fully reported and corrected for recent scale changes. Energies of forbidden transitions, such as 1s-2s, have been determined from redundant combinations of K- and L-series measurements. Transition energies have been calculated relativistically including relaxation to all orders, correlation to second order, and QED effects. Agreement between experiment and theory is of the order of 0.1 eV, except for transitions involving 3s holes where it is 1 eV.
