The three-body wave function built on the basis of the Gaussian function, calculated using the three- body Hamiltonian with the Pauli blocking operator is studied. As an example, the wave function of the ground state of the 9 Be was taken. Analytical expressions are presented for the overlap matrix elements of the basis function for both basic and alternative set of relative Jacobi coordinates. The correlation densities of the wave function are calculated and illustrated depending on the set of orbital quantum numbers.

In work considers the results of studies of the phase composition and mechanical-tribological properties of Ni-Cr detonation coatings obtained at different values of the volume of filling the detonation barrel with an explosive acetylene-oxygen mixture. Analysis of the obtained experimental results indicates that the phase composition and properties of detonation coatings strongly depend on the technological parameters of spraying. When the barrel is filled with an explosive gas mixture of 40%, the coating is not dense enough, with noticeable boundaries between individual particles, which may be the result of insufficient heating and acceleration of the particles of the sprayed powder. It is determined that when the volume of filling the detonation barrel with an explosive mixture is up to 60%, there is a widening and a decrease in the intensity of the main peaks. Higher values of microhardness were obtained at 50% filling of the barrel. The results of tribological tests of coatings showed that the coating applied when filling the detonation barrel with an explosive mixture of up to 60% has a lower coefficient of friction than other coatings.

Using the tagged neutron method at the "TANGRA" facility at Frank Laboratory of Neutron Physics of the Joint Institute for Nuclear Research based on the ING-27 standard neutron generator, a study of the 14.1 MeV inelastic neutron scattering reaction on different nuclei was carried out. The angular distribu- tions of γ - quanta accompanying inelastic neutron scattering on atomic nuclei were measured. This article presents a GEANT4-based program that allows calculating the interaction of fast neutrons with matter and simulating the experiment and also presenting the results of the experiment in a convenient and visual form. Using the written program, optimal target parameters were determined. The algorithm used by the program is given in this work. The general description of the experimental installation, data collection and processing systems is given.

This paper examines the influence of electrolyte-plasma surface hardening on the structure and micro- hardness of wheel steel mark 2. In the work electrolyte-plasma surface quenching was carried out in an electrolyte made from an aqueous solution of 10% carbamide (NH 2 ) 2 CO + 20% sodium carbon- ate Na 2 CO 3 . The work investigated the strength limit, fluidity and wear intensity of the wheeled steel after electrolyte-plasma surface quenching. After electrolytic-plasma surface quenching, a batch, high-temperature plate and low-temperature plate martensit is formed on the surface of the sample. Investigations have been carried out on microhardness determination on cross-section of wheel steel samples after quenching in aqueous solution of electrolyte. It is found that after electrolytic-plasma surface quenching, the microhardening values of this hardened surface layer increased on ≈ 3 times compared to the steel matrix, and the thickness of the hardened layer is 1000-1500 µ m. According to the results of the scanning transmission electron microscopy, the electrolyte-plasma surface quenching caused a change in the morphological constituents of steel mark 2. In the initial state, the matrix of steel is a α -phase, the morphological components of which are fragmented unfragmented ferrite and pearlite.

In this paper, we study the angular features of the signal and background processes of the associated production of the Higgs boson with W boson. Signal and background processes are generated using the CompHEP generator. Monte Carlo data is processed in ROOT software. In the course of studying the basic kinematic properties it was found that the shape of the distributions of the angular variables di ff ers for the signal and background processes. The presence of the spin e ff ect makes it possible to consider the di ff erence between the distributions of angular variables. The observed deviations can potentially reduce the background relative to the signal.

This work is devoted to investigations of nickel nanotubes behavior under influence of swift heavy ion irradiation. High-energy irradiation initiates damage process inside nanostructures and can cause the appearance of new phases with interesting properties. To understand the basic principles of the evolution of structural and magnetic parameters of nanostructures under the influence of high-energy processes, detailed study of nickel nanotubes irradiated with various fluences of Fe 7 + ions was carried out.

The present work describes the procedure for testing the suitability of a polyethylene terephthalate film (after irradiation with heavy ions it is widely used in various fields) as an alpha-track detector. The test was carried out in order to determine the prospects for the use of this film in studies evaluating the indoor and outdoor radon concentrations. The study was conducted using a radionuclide source of alpha particles Am-241. Irradiated film samples were chemically treated. In order to further compare the results, unirradiated film samples were also chemically etched under the same conditions. To determine thepresenceoftracks, compareandanalyzetheirparameters, allsampleswereexaminedusingascanning electron microscope. SEM images of the investigated samples are shown. The results obtained showed the unsuitability of using these films for registration of alpha particles. Currently, studies of the indoor and outdoor radon concentrations are being carried out using solid-state nuclear detector LR-115 based on cellulose nitrate.

The analysis of the experimental data shows that the processes of gas adsorption and radiation defects accumulation in metal oxides correlate with each other and most likely can be described in terms of equivalent kinetic equations. Given this circumstance, the kinetics of accumulation of radiation defects in oxides of di ff erent metals was analyzed. The obtained equations were used to analyze: a) the kinetics of accumulationofradiationdefectsindi ff erentoxidecompounds; b)thedataonthedestructionofradiation-induceddefectsintheatmosphereofdi ff erentgases, andonthekineticsofabsorptionbyoxidesofoxygen, hydrogen, and carbon dioxide molecules. The results of such analysis are systematized and are given in the form of a table. The following conclusions were made: 1. The quantum yield of radiation defects increases monotonically with growth of the temperature of processing, tending to a certain limit value. 2. The constant of destruction of radicals from ionizing radiation increases as well. 3. The ratio of the number of surface and bulk defects in di ff erent oxides can be arranged in the following series: silicon oxide > beryllium oxide > aluminum oxide. Thus, the most optimal (convenient) material for creating absorbing systems by energy intensity is silicon dioxide, and by adsorption e ffi ciency is beryllium oxide.

Neutron transfer and nuclear breakup processes in reaction with weakly bound nucleus 11 Li at energies near the Coulomb barrier are investigated in the framework of the time-dependent Schrödinger equation. The evolution of probability density of outer weakly bound neutrons of 11 Li in the collision with 208 Pb was studied. The probabilities and cross sections of outer neutrons removal (breakup processes and transfertotargetnucleus)werecalculated. Theoreticalpredictionsofthetwo-neutronremovalprobability values were obtained for angles from 140 ◦ to 180 ◦ . The theoretical results have close similarity with experimental data for the two-neutron removal in reaction 208 Pb ( 11 Li, 9 Li ) .
