Semiempirical analysis of electron scattering cross sections in N2O and CO2
Cechoslovackij fiziceskij zurnal - Tập 54 - Trang C742-C746 - 2004
T. Wróblewski, G. P. Karwasz, H. Nowakowska, J. Mechlińska-Drewko, V. T. Novaković, Zoran Lj. Petrović
Results of swarm analysis of electron scattering cross sections in nitrous oxide and carbon dioxide are presented — experimental diffusion coefficients are compared with numerical solution of the Boltzmann equation. Total cross sections for both N2O and CO2 exhibit similar resonant, structure and diffusion and drift coefficients are also similar. However, our analysis shows that values of partial ...... hiện toàn bộ
Quantized levitation by multiply-connected superconductors
Cechoslovackij fiziceskij zurnal - Tập 46 - Trang 2331-2332 - 1996
Stephen B. Haley, Herman J. Fink
A mesoscopic superconducting ring levitating a magnetic micro-sphere in a gravitational field exhibits two remarkable features: a) a small set of distinct, quantized, temperature dependent levitation and suspension states, b) a suppercurrent δ×H that differs from the quantum currentR(ψ*pψ). Quantized levitation, suspension, and trapped states exist when the micro-sphere is held in equilibrium by t...... hiện toàn bộ
On the representation theory of quantum Heisenberg group and algebra
Cechoslovackij fiziceskij zurnal - Tập 44 - Trang 1019-1027 - 1994
Demosthenes Ellinas, Jan Sobczy
We show that the quantum Heisenberg groupH q (1) and its *-Hopf algebra structure can be obtained by means of contraction from quantumSU q (2) group. Its dual Hopf algebra is the quantum Heisenberg algebraU q (h(1)). We derive left and right regular representations forU q ...... hiện toàn bộ

Elimination of systematic errors in applied accurate lattice parameter measurements

Ion waves in a partially ionized gas in an external electric field
Cechoslovackij fiziceskij zurnal - Tập 18 - Trang 1602-1609 - 1968
L. Aubrecht
The propagation of longitudinal acoustic waves in the ion gas in an external electric field is studied theoretically. The results are compared with properties of waves in space without the external field. The phase velocities, damping factors and the influence of parameters of the gas on the properties of ion waves is discussed.
ПОЛЕ ПЕРЕМЕННОГО ДИП ОЛЯ В НЕОДНОРОДНОМ ПОЛУПРОСТРАНСТВЕ

Oldřich Praus
Рассматривается эле ктрическое поле низк очастотного диполя, помещенного на повер хности горизонтальн о расслоенной земли. Предполагаем, что зем ная кора образована п араллельным слоем с удельной проводимо стью σ1, базис которог о уходит в бесконечно сть и обладает удельной п роводимостью σ2. Из об щего решения выведен а постоянная и перемен ная составляющие эле ктрического поля и ук аза-ны возмож...... hiện toàn bộ
Evolution on Z-pinch in argon-filled capillary
Cechoslovackij fiziceskij zurnal - Tập 50 - Trang 1043-1050 - 2000
P. Vrba, K. Koláček, M. Vrbová, J. Schmidt, V. Boháček
A capillary plasma Z-pinch as an alternative active medium of soft X-ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self-consistent solution of the so called “snow-plow” model of plasma pinch together with feeding double-resonance circuit. The calculated development of the current as well as the evaluated pinch time are in good agreement with the...... hiện toàn bộ
