ABSTRACT
Drift instabilities in current sheets with or without the guide field are investigated with a newly developed improved electrostatic dispersion relation. Traditional (local) theories of lower-hybrid drift instability typically assumes small electron drift speed, and expand the electron distribution function in Taylor series. This approximate treatment is removed in this paper. The resulting formalism is uniformly valid for an arbitrary magnitude of relative ion and electron drift speeds, and is valid for an arbitrary strength of the guide field.

    The X-ray topographs of diamond crystals of different perfection degrees have been obtained using the quasiforbidden 222 reflection. It has been shown that the use of such reflections in X-ray topography makes it possible to study the distribution of the defects affecting the electron density...

    The electron density at the nucleus ρ(0) and radial expectation values 〈rn〉 (n=-2–10) of the ground state for lithium-like systems from Z=11 to 18 are calculated with the full core plus correlation wave functions. By using these obtained expectation values, accurate...
