“…Since Costa et al [35] [35] and those of Natarajan [36], as well as with other available experimental data. For Al, the calculated energy is slightly higher than our result, but the values are consistent within the combined error [33]. At higher Z, theory underestimates the experimental energies for both the Kα h 2 and Kα h 1 lines.…”

“…The upward energy shift of the Kα h 2 L 1 transition is due to the reduced screening. For Al, the KβL 2 satellite transitions overlap with the Kα h x-ray hypersatellite spectrum, making the data analysis more complicated [33]. In turn, the Si hypersatellite x-ray spectrum is affected by the first-order KβL 1 satellite components shown in the lower panel of Fig.…”

Single-photon double K-shell ionization of low-Z neutral atoms in the range 12 Z 23 is investigated. The experimental method was based on measurements of the high-resolution Kα h hypersatellite x-ray spectra following the radiative decay of the K-shell double-vacancy states excited by monochromatic synchrotron radiation. The photon energy dependence of the double K-shell ionization was measured over a wide range of photon energies from threshold up to and beyond the maximum of the double-to-single photoionization cross section ratios. From the high-resolution x-ray emission spectra the energies and linewidths of the hypersatellite transitions, as well as the Kα h 1 :Kα h 2 intensity ratios, were determined. The relative importance of the initialstate and final-state electron-electron interactions to the K-shell double photoionization is addressed. Physical mechanisms and scaling laws of the K-shell double photoionization are examined. A semiempirical universal scaling of the double-photoionization cross sections with the effective nuclear charge for neutral atoms in the range 2 Z 47 is established.

The electron-induced L 3 M two-step double ionization cross sections of metallic Pd were determined experimentally for incident electron beam energies ranging from the double ionization threshold up to 18 keV. The double L 3 M ionization cross sections were derived from the intensity ratios (I LαM :I Lα ) of the resolved M satellites to the parent diagram lines. The sample was bombarded with monoenergetic electrons from an energy-tunable 20-kV electron gun. The diagram and M-satellite x-ray lines were measured by means of high-resolution x-ray spectroscopy, using a reflection-type von Hamos bent crystal spectrometer. The two-step partial cross sections were determined by subtracting from the measured total double ionization cross sections the contributions due to the shake process and L 1 -L 3 M 4,5 Coster-Kronig transitions. Despite the thick target employed in the present study, the dependence of the two-step cross sections on the incoming electron energy could be derived using a target slice decomposition method. It is shown that the obtained energy dependence can be well reproduced by the semiempirical parametrization model of Pattard and Rost.

Photoionization of heliumlike targets accompanied by transition of the residual ions into the arbitrary nl state is studied. The method of nonrelativistic perturbation theory with respect to the interelectron interaction is employed. Cross sections are deduced in the form of universal scalings, which hold for nonrelativistic energies including the near-threshold range. Numerical calculations are compared both with available experimental and with theoretical results.
