The research methods

The researches of real crystals, mainly (experiments), are of fundamental character. A majority
of these researches belongs to the sphere of solid-state radiation physics. At different stages of
researches there are cases when the obtained results show the possibility of their practical
application and thus, naturally, it becomes necessary to consider the problems from the viewpoint of
materials science (stabilization of laser color centers, dosimetric properties of oxides for detection of
fast neutrons, metals and alloys with shape memory, hydrogenation, nanoparticles, etc.).
The researches in nuclear physics are of special interest, particularly, the research of the
interaction between the polarized neutrons and polarized nuclei. The nuclear precession of neutrons
(nuclear pseudo-magnetism) is studied. The researches are carried out in collaboration with I.Frank
Neutron Physics Laboratory at the International Joint Institute for Nuclear Research (Dubna,
Russia). The experimental equipment developed by us was given just to this Institute where a
multifunctional equipment “Kolkhida” was created on its basis.
