Plasma oscillations of electron gases
Physica, 1960A unifying concept, that of the frequency- and wave number-dependent longitudinal dielectric constant epsilon (k, omega ), is described which offers a simple way to tie together the theoretical approaches to the electron gas and to describe the plasma oscillations.

Plasma physics aspects of tunnel-ionized gases
Physical Review Letters, 1992Tunnel-ionized plasmas have been studied through experiments and particle simulations. Experimentally, x-ray measurements show that the plasma temperature is higher for a circularly polarized laser-produced plasma compared to when linear polarization is used.

Plasma waveguide formation in predissociated clustering gases
Optics Letters, 1998We report on the use of a novel technique to create a plasma waveguide suitable for guiding high-intensity laser pulses in underdense plasmas. A narrow channel of a clustering gas is dissociated with a low-intensity prepulse. This prepulse is followed by a high-intensity, focused laser pulse.

Existence and Stability of Cold Rydberg Gases and Plasmas
Few-Body-Systems, 2004Recently, the spontaneous evolution of an ultracold gas of Rydberg atoms into a plasma has been demonstrated experimentally, as well as the reverse process of plasma recombination into atomic Rydberg states. Here, we discuss the existence and stability properties of the gas and plasma phases over a wide range of initial-state parameters.

Collective Scattering in Gases and Plasmas
1994Plasmas are made of small size charged particles, that behave according to the reciprocal Lorentz-Maxwell electrodynamics: From Lorentz forces, particles are accelerated by electromagnetic field; and in turn, charged particle acceleration creates new e.m. waves. These new e.m.

Phenomena in gases and plasmas with negative ions
Uspekhi Fizicheskih Nauk, 1993This review is devoted to the phenomena induced by negative ion processes in weakly ionized gases and plasmas. It briefly describes the electron attachment and detachment processes. The consideration focuses on the salient features of charged particle transport in electronegative gases.

Elementary Processes in Gases and Plasmas
2018Elementary processes involving atoms, electrons and ions are analyzed. Peculiarities of cross sections and rate constants as characteristics of these processes are considered. Various pair and three body collision processes are considered as elastic electron-atom scattering, processes of excitation, quenching and ionization of atoms by electron impact,

Thermal and plasma nitridation of GaSe crystal
Vacuum, 2002Abstract The possibility of the nitridation of gallium selenide followed by the GaN growth is demonstrated. We used the partial pressures diagram method to study the equilibria during the GaSe thermal nitridation process. Experimentally we obtained the wurtzite GaN by the nitridation of GaSe in NH 3 flow in the temperature range 1000–1200 K for 1 h ...

Plasma destruction of flue gases
IEE Colloquium Pulsed Power '97, 1997Nonthermal electrical discharges with sufficiently high electron energies can reduce NO (nitric oxide) levels in air-like gases (e.g. flue gas) to zero and will, with sufficiently high energy input, also reduce the concentration of nitrogen dioxide (NO/sub 2/) and thus of total NO/sub x/, besides destroying various other pollutants.
