Some optical properties of the spiral inflector
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 1999)
This paper compares some optical properties of different spiral inflectors using the program CASINO. The electric field distribution in the inflectors has been numerically calculated from an electric potential map produced ...
Soliton-induced modification of the speed of sound in quasi-one-dimensional molecular crystals
(Journal of Physics: Condensed Matter, 1998)
The influence of the anharmonic vibron-phonon coupling, arising on account of a dressing effect, on the characteristics of the lattice subsystem in quasi-one-dimensional molecular crystals was examined within the pseudo-harmonic ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Detuned primary RF coupling system for variable frequency cyclotrons
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 1998)
A new concept of impedance matching for an RF amplifier coupled to a cyclotron cavity, named detuned primary coupling, is proposed. It does not require the motion of the coupling loop in vacuum and the matching for different ...
