Issues addressed and main goals of research:
Experimental and theoretical investigations of symmetry breaking effects in reactions with neutrons and fundamental properties of the neutron to test the parameters of the Standard Model and search for "new physics". Investigation of the properties of excited nuclei, reactions with emission of charged particles, fission physics. Obtaining of relevant data for astrophysics, nuclear power engineering and nuclear waste transmutation problem using neutron- and gamma-induced reactions. Application of neutron physics methods in other fields of science and technology. Development and construction of detectors of neutrons and other ionizing radiation, as well as applied methods in nuclear physics with neutrons. Development of the Intense REsonance Neutron Source (IREN) and the experimental base at the IREN and IBR-2 facilities.
Expected
results in the current year:
Investigations
of violations of fundamental symmetries
in neutron-nucleus
interactions and related data
Measurement of energy spectra and forward-backward emission asymmetry of gamma-rays in resonances.
Measurement of yields of rare fission modes of 252Cf.
Measurement of gamma-ray yields in reactions with 14 MeV neutrons.
Measurements of prompt fission neutrons (PFN) for 235U in the resonance region.
Measurement of the cross section for 171Yb(n,α)168Er and (n,α) reaction cross sections on gas samples (N, O, F, Ne, Ar) at En 3-5 MeV.
Measurement of the forward-backward asymmetry of the 14N(n,p)14C reaction at En=100-700 keV on EG-5 and of the 35Cl(n,p)35S reaction at En=0.1-1.0 keV on IREN.
Investigation of fundamental properties of the neutron, UCN physics:
Studying the possibility of creating a radiation-resistant UCN guide with both losses and fraction of non-specular reflections ~ 10-3 per collision.
Simulation of the propagation of very cold neutrons (VCN) in various diamond nanopowders to optimize their parameters and increase the efficiency of VCN extraction from the source.
Investigation of the effect of the density of diamond nanopowders on the properties of slow neutron reflectors developed on their basis.
Investigation of the possibility of increasing the intensity of the UCN source based on the idea of temporary focusing using alternating magnetic fields and (or) resonant spin-flippers in a strong magnetic field.
Design of a neutron-moderator-device for a UCN source based on a pulsed reactor.
Theoretical
study of neutron scattering on nuclei moving with acceleration.
Creation of an experimental setup for measuring the R-effect in fission by polarized neutrons at the IBR-2 reactor.

Investigation of optical and electronic properties of semiconductor materials using X-rays at the EG-5 accelerator.
Modernization of the EG-5 accelerator and its infrastructure.
Analysis of archaeological, biological and ecological samples by nuclear-physics methods at the IREN, REGATA2 facilities and using the laboratory equipment.
Completion of the modernization of the REGATA facility and its pneumatic conveying system at the IBR-2 reactor.
Creation of a charged particle spectrometer on the 1st channel of IREN.
Development of the IREN facility
Providing the neutron beam time from IREN for physics experiments.
