Investigating the luminescent properties of organic semiconductors, in particular poly-N-vinilcarbazol, the abnormal phosphorescence, i.e. nonmonotonic decrease of attenuation, was found, especially in the pure. The range of times, characteristic for abnormaliy, in the case with poly-N-vinilcarbazol is less, than for gelatin.

The theory of inverse problems for the particle transport equation is one of the rapidly developing areas of modern mathematics. This article discusses the continuity of the solution of inverse problems for the radiative transfer equation in multi-zone regions from R. In fact, the inverse problem is studied for the non-stationary radiative transfer equation, which consists in simultaneously finding the scattering coefficient ss and radiation intensity u. In this case, it suffices to prove the continuity of the solution of the inverse problem from R with respect to additional information. In this paper, we study the local properties of the classical solution of the single speed time-dependent equation considered in a multi-zone domain.

The linear and non-linear optical characteristics of new polymeric materials based on polymethyl methacrylate doped with β-diketonates of boron difluoride are studied in the article. The obtained samples showed a high output of one- and two-photon fluorescence and high two-photon absorption coefficients. Spectral characteristics of the samples enable the use of the studied materials as fluorescent concentrators of solar energy.

In this paper, we consider the analytic functions of a complex variable with small parameters generated by some operators. We study the asymptotic behavior of a function with respect to a small parameter. The problem is solved using line-level harmonic functions. The analytic domain of the function is divided by some lines into parts, and in some parts the limits (by a small parameter) exist, but in others they are infinite or do not exist.

The analysis of the gravitation process mechanism is carried out using the condition of a stationary state in wave-particle interactions and within the framework of non-relativistic mechanics. The author obtained an equation of the functional dependence of the constant of gravity on the electric constant. It is assumed that gravity is the wave contribution from the mass of charged particles when they move in the field of central forces.

The author uses a mathematical model describing the propagation of a multiphase flooded jet caused by the damage to the oil-producing structure or the marine pipeline used for the transportation of hydrocarbons. The flow features of multiphase and single-phase (gas) jets are studied. The author also studied the effect of hydrate formation on the jet parameters. The integral Lagrange method is used to calculate the thermophysical parameters. As a result of these calculations, the author obtained the dependences of temperature and velocity on the vertical coordinate. Data analysis of dependencies allows predicting jet behavior and study the possibilities of application of devices for leak detection.

The paper presents the results of structural studies of CeO2 buffer layers grown by pulsed laser deposition on single-crystal substrates of r-Al2O3 ( ) at a substrate temperature of 750°C. It was shown experimentally that when the oxygen pressure changes during growth, while maintaining the remaining growth parameters unchanged, it is possible to obtain buffer layers with different crystallographic orientations: at an oxygen pressure of 0.002 mbar, the buffer layers have an orientation of (111), and at an oxygen pressure of 0.2 mbar – (002). The results obtained may be of interest for the preparation of epitaxial films and nanoheterostructures with layers of high-temperature superconductors and doped manganites on r-Al2O3 single-crystal substrates with CeO2 buffer layers.

The photoionization cross sections for the ground and same excited states of 10 ions cesium isoelectronic sequence from Ba+ through Tb10+ are calculated by the relativistic Dirac-Fock self-consistent field method. The energy dependence of the photoionization cross sections and the changes in the threhold values along the isoelectronic sequence are considered. Along with the total photoionization cross sections, the asymmetry parameter in the angular distribution of photoelectrons and the degree of their polarization ara also colculated.
