Magnetic susceptibility of lead sulphide
Cechoslovackij fiziceskij zurnal - Tập 28 - Trang 216-219 - 1978
H. Mikhail, I. Mekkawy
Magnetic susceptibility measurements were carried out on lead sulphide in the form of natural galena crystals, and in the form of crushed powder. The experimental molecular diamagnetic susceptibility value was found to be 93·27×10−6 (in e.m.u./gm.mol.) for the single crystal and 81·84×10−6 for the powdered material. Calculations based on a modified Slater-Angus method showed that the type of bondi... hiện toàn bộ

Population of the excited Ne atoms in 3d levels by dissociative recombination in the neon afterglow plasmas at room temperature
Cechoslovackij fiziceskij zurnal - Tập 40 - Trang 191-202 - 1990
Ĺ. Malinovský, P. Lukáč, J. Trnovec, C. J. Hong, A. Tálsky
The paper deals with the optical investigation of the dissociative recombination of Ne 2 + molecular ions with electrons in the afterglow period of d.c. and high-frequency glow discharges. It has been confirmed experimentally that the dissociative recombination produces excited atoms in the Ne (3p i ) states and in the Ne (3d j states at room electron temperature. Then, the normalized partial reco... hiện toàn bộ
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
Compact coaxial driver for small-size Z-pinch
Cechoslovackij fiziceskij zurnal - Tập 45 - Trang 209-213 - 1995
J. Rauš, A. Krejčí
The presented one-capacitor pinch driver, designed as a compact coaxial structure (including spark-gap and discharge section) consistent with the capacitor output, generates a current of 200 kA with 700 ns quarter-period, suitable for studying the optimization of Z-pinch radiative characteristics. The driver is described, measurements of its parameters summarized, and relations to our previous and... 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 (h(1)) as acting on its dualH q (1). Imposing conditions on the right representation, the left representation is reduced to an ... hiện toàn bộ
