Main directions of scientific activity: 

• Experimental researches of cross-sections for the interactions of average energy neutrons with stable atom nucleus by the neutron - and g - spectrometry precision methods.
• Researches of scattering mechanisms of the fast neutrons by odd nucleus. Structure of the odd nucleus excited condition.
• Methods of the average resonant parameters definition from the cross-sections of neutron inelastic scattering by the even-even nucleus in the field of the low energies.
• Theory of the diffraction repeated scattering for the inelastic and elastic scattering process of the hadrons by nucleus.
• Development and manufacturing of various devices with content of tritium.

The most important scientific results: 

• The variant of generalized optical model with primary absorption in the one-background channel is offered and proved. The model of the neutrons scattering at the deformed soft nucleus is developed.
• Spectrometer complexes for the research of interaction of neutrons with atom nucleus in a wide energy range on the basis of the low-voltage neutrons generator, the electrostatic accelerator and the reactor WWR-M are developed and created.
• Full cross-sections, angular and energy dependences of the partials cross-sections for the nucleus of constructional reactor materials in a wide energy range are received. Periodicity in properties of nucleus at intermediate excitations in depending on number of neutrons and protons is established
• Energy and isotope-backs dependences of the optical model parameters are established. The role of fluctuations and correlation partials resonance width effects on theoretical cross-sections of neutron scattering is investigated. Relative direct and compound mechanisms contributions in cross-sections of inelastic and elastic neutron scattering by the even-even isotopes of the nucleus with average atoms weight in the wide neutron energy area are determined.
• By slow neutron scattering method the density of photon states of some metals, alloys, ion crystals, substances with high-temperature superconductivity was obtained characteristics of the crystal electric field of alloys based of rare-earth elements.
