Vibrational structure of the B-X system of isotopic AgO molecules
(Spectroscopy Letters, 1999)
Spectra of (AgO)-Ag-107-O-18 and (AgO)-Ag-107-O-16 molecules have been obtained in a low-pressure are in oxygen atmosphere, and recorded with medium dispersion. Vibrational assignments for the bands of B(2)Pi-X(2)Pi system ...
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 ...
The role of surface defects in HOPG on the electrochemical and physical deposition of Ag
(Journal of the Serbian Chemical Society, 1999)
The role of defects on a substrate surface during the initial stages of nucleation and growth of Ag deposited electrochemically and physically on highly oriented pyrolytic graphite (HOPG) has been observed ex situ by ...
Thermal diffusivity of the candidate standard reference material cordierite
(High Temperatures: High Pressures, 1999)
The results of an international programme carried out to qualify transfer or reference standards for thermal transport properties, thermal conductivity and thermal diffusivity, in the range between 1 W m(-1) K-1 and 5 W ...
Phase composition and fracture toughness of Si3N4-ZrO2 with CeO2 additions
(Ceramics International, 1999)
Zirconia toughened Si3N4 was prepared with addition of CeO2 by applying hot pressing technique. Phase composition, densification, fracture toughness and hardness were investigated as a function of hot pressing temperature ...
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 ...
Surface properties of metal ions modified silicas
(Colloids and Surfaces. A: Physicochemical and Engineering Aspects, 1999)
The surface properties of metal (alkali and alkaline earth) modified silica beads were investigated by the inverse gas chromatography method. Silica beads, obtained from silica sol, were characterized by their specific ...
Fully relativistic description of extraordinary and quasilongitudinal waves propagating in plasmas
(Plasma Physics and Controlled Fusion, 1999)
Extraordinary and quasilongitudinal waves propagating at an arbitrary angle with respect to the steady magnetic field are investigated within the fully relativistic theory. The results of the present paper complement the ...
Prefission neutron multiplicities and the fission modes of Th-226
(Europhysics Letters / EPL, 1999)
The neutron spectra associated to the two fission modes of Th-226 have been measured in coincidence with the fragment yields of the O-18 + Pb-208 reaction at E-lab = 78 MeV. The pre- and post-fission multiplicities and ...
Influence of additives on the properties of spherical nickel particles prepared by ultrasonic spray pyrolysis
(Journal of Materials Research, 1999)
Ideal spherical nonagglomerated Ni particles (mean diameter 0.62-1.12 mu m) were prepared by ultrasonic spray pyrolysis of NiCl2 aqueous solution in the presence of 0.1 mass% of Pd, Cu, or Ni in an H-2-N-2 atmosphere at ...
