Cu K^hα_1,2 hypersatellites: Suprathreshold evolution of a hollow-atom X-ray spectrum

Photoexcitation by synchrotron radiation was used to measure the high-resolution pure Cu K^h α_1,2 hypersatellite spectrum. Parameters such as the shift from the diagram lines, splitting and intensity ratios were calculated in this context. The measured values were found to correlate with the ab initio Dirac-Fock calculations. The three-dimensional transition elements were investigated for implication of coupling, correlation and interatomic correlations in the Z variation theories.
