[en] The study of electromagnetic transitions between 5/2^- and 3/2⁺ bands for some terbium nuclides was done. The intensities of gamma-transitions were determined and compared with Alagi rule. For better concordance the existence of wave function admixture 5/2^-3/2^-[521] in 5/2^-5/2^-state was supposed and mixing parameter was determined.(A.A.D.)

[en] X-ray emission analysis with the use of Si(Li)-detectors was applied for analysis of multi-component alloys containing both heavy(lead) and light elements(zinc, silver, antimony) and for monitoring the doping additions during production of refractories. (A.A.D.)

[en] The study of derivatives of dialcoxytiophosphorous, methyl- and phenolphosphine and cyclic phosphorous acids for extraction of precious metals was done. It was shown that they have satisfactory extractive properties in extraction of gold, silver, platinum and palladium. Radioisotopes ¹⁹⁸Au, ¹¹⁰Ag, ¹⁰³Pd and ¹⁹⁷Pt were used for isotopic exchange. (A.A.D.)

[en] The first data on changes of cesium-137 radionuclide distribution in soils of Samarkand region(Uzbekistan) during last 30 years are presented. Gamma-spectra of samples were measured by Ge(Li)-detector. It was shown that considerable changes in cesium -137 distribution took place. (A.A.D.)

[en] The method of accounting of background in natural radioactivity spectra of environment's samples was elaborated. Method includes determination for each set of detectors and Marinelli vessels used for samples packaging background spectra by simulation experiment. (A.A.D.)

[en] In this work we consider an approach to formation of images of studied object in the real time of data acquisition taken in the course of positron-emission tomography inspection. The method assumes selection of some flat fantom object having arbitrary shape. Then, on the basis of the proposed processing of each trajectory (of annihilation γ-quanta, counted in coincidence) with following reading it in computer memory, the working space of tomograph is formed with the active centers, reproducing the fantom-object. For given coordinate system the algorithm for separating the detectors, determining the trajectories of annihilation γ-quanta with extraction of the corresponding cells on this trajectory was developed. Using Fortran-32 on IBM-486 a computer program SCANNER was elaborated for the data processing, which allows to fulfill a large number of model calculations. The obtained images have a good correspondence to respectively different initial fantom-objects. (author)

[en] The stationary values of amplitudes, cross sections and overlapping functions for given values of total cross section of total elastic scattering were obtained using unitarity conditions and Hankel integral representations. The comparison of experimental data on differential cross sections of pp-and ppbar- scattering and stationary values was done.(A.A.D.)
