Role of resonant inelastic x-ray scattering in high-resolution core-level spectroscopy of actinide materials
K. O. Kvashnina, S. M. Butorin
This paper provides a brief overview of applications of advanced X-ray spectroscopic techniques that take advantage of the resonant inelastic X-ray scattering (RIXS) in the hard an…
The chemical state of complex uranium oxides
K. O. Kvashnina, S. M. Butorin, P. Martin +1
We report here the first direct observation of U(V) in uranium binary oxides and analyze the gradual conversion of the U oxidation state in the mixed uranium systems. Our finding c…
Long Term H-Release from Amorphous Carbon Evidenced by in Situ Raman Microscopy under Isothermal Heating
Cedric Pardanaud, C. Martin, G. Giacometti +6
We study the kinetics of the H release from plasma-deposited hydrogenated amorphous carbon films under isothermal heating at 450, 500 and 600 {\degree}C for long times up to severa…
Raman study of CFC tiles extracted from the toroidal pump limiter of Tore Supra
Cedric Pardanaud, G. Giacometti, C. Martin +10
The structure of six tiles extracted from the erosion and deposition zones (thin and thick deposition) of the Tore Supra toroidal pump limiter (TPL) have been analysed in the frame…
Influence of the U3O7 domain structure on cracking during the oxidation of UO2
Lionel Desgranges, Hervé Palancher, M. Gamaléri +5
Cracking is observed when a UO_{2} single crystal is oxidised in air. Previous studies led to the hypothesis that cracking occurs once a critical depth of U_{3}O_{7} oxidised layer…
