We observe the formation in a single-photon transition of two core holes, each at a different
carbon atom of the C 2 H 2 molecule. At a photon energy of 770.5 eV, the probability of this 2 …

The x-ray atomic properties of nickel (Ni) were investigated in a unique approach combining
different experimental techniques to obtain new, useful and reliable values of atomic …

The dominant decay pathways of argon 2 p− 2 double-core-hole states have been
investigated using synchrotron radiation and a magnetic-bottle-type spectrometer coupled …

Experimental evidence for the correlated two-electron one-photon transitions (1 s-2→ 2 s-1
2 p-1) following single-photon K-shell double ionization is reported. The double K-shell …

We propose a novel approach for the theoretical analysis of the photoinduced high-
resolution K h α 1, 2 x-ray hypersatellite spectra, which allows us to obtain reliable values of …

X-ray spectra of K-shell hollow krypton atoms produced in single collisions with 52–197-
MeV/u X e 54+ ions are measured in a heavy-ion storage ring equipped with an internal gas …

Abstract The L subshell Coster‐Kronig (CK) transition factors of Gd have been
experimentally determined by means of two different experimental approaches and …

This paper investigates the capability of the two-step (TS) approaches in calculating the
cross section of the electron-impact double ionization (DI) of ions. The TS approach …

We report measurements of the nonresonant x-ray emission spectroscopy (XES) from Ni
metal in an energy range spanning the K β diagram line, valence-to-core emission, and …

We have built and commissioned a novel standalone multi-crystal x-ray spectrometer
(MOSARIX) in the von Hamos configuration based on highly annealed pyrolytic graphite …
