Diagram, valence-to-core, and hypersatellite Kβ X-ray transitions in metallic chromiumSpectroscopyThe financial support of the Swiss National Science Foundation (Grant No. 200020-146739) is acknowledged by F.?Z., J.?H., and J.-Cl.?D. M.?G. acknowledges the support of the FCT, under the Contract No. SFRH/BPD/92455/2013 and the project PTDC/FIS-AQM/31969/2017, ?Ultra-high-accuracy X-ray spectroscopy of transition metal oxides and rare earths.? This work was also partly supported by the research center grants nos. UID/FIS/04559/2013 to LIBPhys-UNL, and UID/MULTI/04046/2013 to BioISI, from the FCT/MCTES/PIDDAC.We report on measurements of the Kβ diagram, valence-to-core (VtC), and hypersatellite X-ray spectra induced in metallic Cr by photon single and double K-shell ionization. The experiment was carried out at the Stanford Synchrotron Radiation Lightsource using the seven-crystal Johann-type hard X-ray spectrometer of the beamline 6-2. For the Kβ diagram and VtC transitions, the present study confirms the line shape features observed in previous works, whereas the K h β hypersatellite transition was found to exhibit a complex spectral line shape and a characteristic low-energy shoulder. The energy shift of the hypersatellite relative to the parent diagram line was deduced from the measurements and compared with the result of extensive multiconfiguration Dirac–Fock (MCDF) calculations. A very good agreement between experiment and theory was found. The MCDF calculations were also used to compute the theoretical line shape of the hypersatellite. A satisfactory agreement was obtained between the overall shapes of the experimental and theoretical spectra, but deviations were observed on the low- and high-energy flanks of the hypersatellite line. The discrepancies were explained by chemical effects, which were not considered in the MCDF calculations performed for isolated atoms.LIBPhys-UNLDF – Departamento de FísicaRUNZeeshan, FaisalHoszowska, JoannaDousse, Jean ClaudeSokaras, DimosthenisWeng, Tsu ChienAlonso-Mori, RobertoKavčič, MatjazGuerra, MauroSampaio, Jorge MiguelParente, FernandoIndelicato, PaulMarques, José PiresSantos, José Paulo2019-10-02T22:42:08Z2019-01-012019-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.1002/xrs.3019eng0049-8246PURE: 12942723http://www.scopus.com/inward/record.url?scp=85061447049&partnerID=8YFLogxKhttps://doi.org/10.1002/xrs.3019info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T04:36:56Zoai:run.unl.pt:10362/83057Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:36:16.235787Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
