Study of the Electronic Structure of Ce-based Heavy-fermion Systems Exposed to the Low-energy Neutrino Dense Flux

The class of compounds based on f-elements (Ce) attracts great attention because of their unusual properties. They are characterized by a heavy-fermion state, which occurs in them under certain external actions. Heavy-fermion materials have unique properties. The objective of the work is the investigation of a change in the electronic structure in a number of Ce-based systems under the action of a dense neutrino flux in order to develop the technology for the essential change of material properties. To increase the density of the neutrino flux by several orders of magnitude, the phenomenon of diffraction is used. The investigation of the electronic structure of Ce-based systems on the electron magnetic spectrometer using the x-ray electron method and the calculations of the density of states at different temperatures has shown the decrease in the intensity of the localized resonance maximum near Fermi level with increasing temperature.
