Towards the definition of the optimum height of voluminous cylindrical sources in gamma-ray spectroscopy
(Applied Radiation and Isotopes, 1999)
We show that for cylindrical voluminous sources in gamma-ray spectroscopy the relative error of the spectral intensity of a low-energy spectral line, as the height of the source increases, saturates faster than the spectral ...
Self-organization in a dissipative three-wave interaction
(Physical Review E, 1999)
A nonlinear three-wave interaction in an open dissipative plasma model of a stimulated Raman backscattering is studied. An anomalous kinetic dissipation due to electron trapping and plasma wave breaking is accounted for ...
Equivalence of two parallel approaches to the cluster variation method: the multisite correlation functions method and the cluster effective fields method
(Physica A: Statistical Mechanics and Its Applications, 1999)
We have analyzed relationship between two parallel approaches to the cluster variation method (CVM) as a theoretical tool for studying statistical properties of binary systems. The first approach to the method uses the ...
Room-temperature luminescence of AgBr quantum dots
(Chemical Physics Letters, 1999)
A new method for the preparation of 25 Angstrom AgBr quantum dots has been developed. The room-temperature emission of size-restricted AgBr crystallites was observed. The emission spectrum of 25 Angstrom AgBr quantum dots ...
Effects of cemented carbide surface pretreatment in combustion flame chemical vapour deposition of diamond
(Thin Solid Films, 1999)
Effects of different pretreatment procedures on WC-6%Co surface modification and some properties of diamond coating deposited by combustion flame CVD on the pretreated surfaces have been systematically studied. The ...
Effects of the pretreatment of a cemented carbide surface on its properties and on the properties of diamond coatings deposited by oxygen-acetylene flame CVD
(Diamond and Related Materials, 1999)
The influence of the pretreatment of the WC (6% Co) surface on its properties (i.e. roughness, grain size and chemical composition) and on the properties of flame-deposited coatings have been studied. The surface treatments ...
Apolipoprotein E gene DNA polymorphism in Serbian population
(Jugoslovenska Medicinska Biohemija, 1999)
The study estimates the distribution of apoE alleles in Serbian population (622 persons) by restriction isotyping of the amplified apoE gene sequence and MADGE analysis. The E2 allele frequency estimated here (0.149) is ...
Gain optimization in intersubband quantum well lasers by inverse spectral theory
(Solid State Communications, 1999)
A systematic procedure is described for the maximization of gain in optically pumped intersubband lasers, via tailoring the quantum well potential. The procedure relies on the inverse spectral theory, which enables shifting ...
New rotational analysis of the B-2 Sigma(+)-X-2 Sigma(+) bands in (GaO)-Ga-69-O-16 and (GaO)-Ga-71-O-16
(Journal of Molecular Spectroscopy, 1999)
In the emission spectrum of the (GaO)-O-16 molecule, the 0-0 and 1-0 bands of the B-X system have been rephotographed by means of conventional high-resolution spectroscopy. Clear resolution on the rotational structure near ...
Enhanced photocorrosion stability of colloidal cadmium sulphide-silica nanocomposites
(Journal of Materials Science Letters, 1999)
This study demonstrates the enhanced photocorrosion stability of colloidal CdS-SiO2 nanocomposite spheres. It is shown that this nanocomposite system can be used for photocatalytic purposes.
