\TA Experimental and theoretical investigations aimed at studies of fundamental 
    properties of the neutron, symmetry breaking effects in neutron-induced 
    reactions, and fundamental interactions of neutrons with nuclei. 
    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. Develop\-ment of the Intense REsonance Neutron Source (IREN) and of 
    the experimental base at IREN and IBR-2M.
