摘要：
The structure of X-ray photoelectron spectra of actinide-containing (An = Th, U, Np, and Pu) murataite ceramic (Ti-Mn-Ca-An-Zr-Al-Fe-O) samples as potential matrices for immobilization of actinide radioactive waste was studied. The elemental composition of the sample surface was analyzed, and comparison with the calculated data for the bulk of the samples was made. The binding energies of the An4f electrons and the parameters of the fine structure of their X-ray photoelectron spectra were determined. These parameters were compared with the corresponding values for the dioxides. © Pleiades Publishing, Inc., 2012.
