“…Tsarev, when him it came time to go into a long scientific trip abroad, he was suggested me to organize conduct of his seminar in the RUDN University, helped by a lightweight access to the RUDN and his international status. In addition in our group at the chair of theoretical physics and mechanics, Faculty of physics, mathematics and natural sciences of RUDN University after several years of experimental research, within one of the main scientific directions of faculty -research in the field of interaction of the electromagnetic radiation with matter, particle physics, physics of metals and alloys aimed at creation of energy-saving technologies and environmentally friendly energy,for the first time managed to observe the neutrons emitted by deuterated ferroelectric in the process of repolarization in an electric field [2], the world's first work on the initiation of nuclear reactions in ferroelectrics. Moreover, the experiment was reliable reproducible.…”
