Propagation of radio waves across a velocity discontinuity in a zero temperature plasma
Cechoslovackij fiziceskij zurnal - Tập 14 - Trang 417-422 - 1964
A non-relativistic treatment of the investigated effect is given. It is shown that a transverse wave incident on the interface of a velocity discontinuity generates reflected and transmitted waves. The intensities of reflected and transmitted electric fields are calculated.
Single-phonon contribution to the hopping conductivity of amorphous solids
Cechoslovackij fiziceskij zurnal - Tập 22 - Trang 1122-1133 - 1972
The electronic d.c. hopping conductivity of amorphous materials is calculated exactly up to the second power of the coupling constant of electrons and acoustic phonons. Its temperature dependence is discussed.
The study of cluster phenomenon at accelerator energies
Cechoslovackij fiziceskij zurnal - Tập 39 - Trang 12-21 - 1989
Correlation between the particles from the proton-nucleus interactions in emulsion at 70 GeV/c is presented through the study of the rapidity gap analysis and compared with the two-particle rapidity correlations. It is observed that the strength of correlation decreases as the size of cluster increases. Asymmetry between the forward and backward components were also studied.
High temperature superconductivity in Sm-Ba-Cu, Sm-Ca-Cu and Y-Ba-Cu oxidized alloys
Cechoslovackij fiziceskij zurnal - Tập 37 - Trang 1203-1204 - 1987
On the possibility of determining crystal size of crystallites and powder samples in the range 10−5−10−3 cm by means of X-rays
Cechoslovackij fiziceskij zurnal - Tập 3 - Trang 69-71 - 1953
Deposition of organic polymers at higher substrate temperatures in atmospheric pressure glow discharge
Cechoslovackij fiziceskij zurnal - Tập 56 - Trang B1377-B1382 - 2006
The atmospheric pressure glow discharge burning in nitrogen with small admixture of organosilicon compounds such as hexamethyldisilazane (HMDSN) or hexamethyldisiloxane (HMDSO) was used for the deposition of thin organosilicon polymer films at deposition temperatures up to 120 °C. The properties of the discharge were studied by means of optical emission spectroscopy and electrical measurements. Me...... hiện toàn bộ
On the theory of “true” three particle scattering
Cechoslovackij fiziceskij zurnal - Tập 30 Số 10 - Trang 1090-1100 - 1980
The Hulthen, Kohn and Schwinger-type variational principles for the phase of “true” three particle scattering is formulated using the method of the hyperspherical basis. The optical theorem for such processes is proved.
A simplified model joining the sheath and the plasma in electronegative plasmas
Cechoslovackij fiziceskij zurnal - Tập 54 - Trang 225-238 - 2004
An extension of the previous work which only dealt with the sheath zone is used to analyze the wall-plasma interaction in electronegative plasmas. Ionization is introduced as the presheath mechanism. This extension includes the joining of the sheath and the plasma solutions. For certain plasma parameters a stratified presheath is obtained. In this case, the plasma and the sheath solutions are matc...... hiện toàn bộ
An “active” target for spin physics: polarizing nuclei in plastic scintillators
Cechoslovackij fiziceskij zurnal - Tập 52 - Trang C689-C694 - 2002
Polarized scintillating targets are now routinely available: protons, deuterons or other nuclei in blocks of scintillating organic polymer, doped with the free radical TEMPO, have been polarized dynamically in a field of 2.5 T in a vertical 3He−4He dilution refrigerator. A 19 mm diameter plastic lightguide carries the scintillation light from the sample in the mixing chamber to a photomultiplier o...... hiện toàn bộ
