Simulations of anomalous stimulated Raman backscattering in a bounded plasma
(Journal of the Physical Society of Japan, 1998)
Temporal pulsations, bursting and incoherence of stimulated Raman backscatter in a bounded, underdense plasma were observed in relativistic particle-in-cell simulations. We show that backscatter complexities, modulated and ...
The role of solitons in charge and energy transfer in 1D molecular chains
(Physica. D: Nonlinear Phenomena, 1998)
The idea that polarons and solitons could play the crucial role in the transport processes in biological structures, has been critically reexamined on the basis of the general theory of self-trapping phenomena. The criteria ...
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 ...
Quantum states which behave classically
(Journal of Physics. A: Mathematical and General, 1998)
We give a definition of quantum states which behave classically based on minimal number of physically reasonable requirements. We prove that an infinite unique class of states exists which satisfies this definition and we ...
Structure and bond length distribution in Hf2Fe and Hf2Co intermetallic compounds
(Journal of Applied Physics, 1998)
The grain structure and interatomic distances in annealed Hf2Fe, as well as in nonannealed and annealed Hf2Co polycrystalline isostructural phases, with unit cells of the Ti2Ni type, ale studied using scanning tunneling ...
Ordinary waves in relativistic plasmas
(Plasma Physics and Controlled Fusion, 1998)
The propagation and absorption of ordinary waves in fully relativistic plasma are investigated. Several interesting effects introduced by the relativistic mass increase associated with an increase in the electron temperature ...
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 ...
Reaction cross sections in Si of light proton-halo candidates N-12 and Ne-17
(Nuclear Physics A, 1998)
Total reaction cross sections, sigma(R), on Si were measured near 40 A MeV for the proton-halo candidate N-12 and the two-proton-halo candidate Ne-17, and were compared with sigma(R) for other light proton-rich nuclei. The ...
Numerical solutions of differential equations of an ionization chamber: plane-parallel and spherical geometry
(Physics in Medicine and Biology, 1998)
A system of reduced differential equations generally valid for plane-parallel, cylindrical and spherical ionization chambers, which is appropriate for numerical solution, has been derived. The system has been solved ...
