ENHANCEMENT OF GAMMA-RAY YIELD FROM FAST NEUTRONS INTERACTION WITH CADMIUM ISOTOPES 

Purpose. This paper presents the results of investigation of γ-ray yield enhancement from natCd(n,xγ) reactions obtained in experiments with 14-MeV neutrons in comparison with theoretical spectrum calculated in Empire code. Methods. The experiment w...

SIMULATION THE YIELDS OF ACTINIDE NUCLEI PHOTOFISSION PRODUCTS AS SOURCES OF DELAYED GAMMA RADIATION FOR THE NEEDS OF ANALYZING THEIR ISOTOPIC COMPOSITION

Purpose. One of the most important tasks of the nuclear industry is to control the non-proliferation of fissile nuclear materials (for example 232Th, 235U, 238U, 239Pu) at all stages of their use (movement, storage, etc.). To successfully solve this problem,...

INFLUENCE OF AMMONIA ON THE OPTICAL PARAMETERS OF PURPLE MEMBRANES FILMS MODIFIED WITH A DETERGENT IN A SOL-GEL MATRIX 

Purpose. This article is devoted to the study of the effect of ammonia in the gas phase and in aqueous solutions on the optical properties of bacteriorhodopsin films in sol-gel matrices. For comparison, we took films obtained by standard methods and films using purple membranes additionally treated wit...

ТЕОРЕТИЧЕСКИЕ РАССЧЕТЫ ФОНОННЫХ СПЕКТРОВ КРИСТАЛЛОВ Cu7GeSe5I И Ag7GeSe5

The model calculations of the dispersions of the phonons for the superionic Cu7GeSe5I AND Ag7GeSe5I crystals was done. The description of the models of all the structures was reduced to the construction of the proper sets of modulation vectors, the definition of the mass modu...

MODEL CALCULATIONS OF DISPERSION DEPENDENCIES OF STRUCTURES OF TYPE BaTiO3 WITH PARTIAL POPULATION OF DIFFERENT CRYSTALLOGRAPHIC POSITIONS

Purpose. The results of model studies of the phonon spectrum of the crystalline structure of the BaTiO3 type are presented. (3+3)-dimensional structures for describing the crystal structure of the perovskite in (2a×2a×2a) a metric and (4a×4a×4a) a superlattice are con...
