Photodetachment diagnostic techniques can help determine densities and temperatures of
negative ions in a variety of scientific devices in which these ions are one of the major …

Extensions of the electrostatic probe technique to situations with negative ions, both
theoretical and experimental, are described. Charged particle distributions and the plasma …

Negative hydrogen/deuterium ions can be formed by processes occurring in the plasma
volume and on surfaces facing the plasma. The principal mechanisms leading to the …

Multi-soliton interaction of nonlinear ion sound waves in a pair-ion–electron (PIE) plasma
having non-Maxwellian electrons including Kappa, Cairns, and generalized two spectral …

A semiempirical analysis is made of the contributions of the two lowest resonant states to
dissociative attachment and vibrational excitation in low-energy collisions of electrons with H …

H− ions formed by volume processes are extracted from a multicusp ion source. It is shown
that a permanent magnet filter together with a small positive bias voltage on the plasma grid …

The development of a microcomputer‐controlled electrostatic probe as a diagnostic
technique is described. The technique uses cylindrical probes and the definitive theory of …

Recombinative desorption of atomic hydrogen on the walls of a gas cell has been observed
to populate vibrational levels up to v= 9. The vibrational populations follow a Boltzmann …

Properties of fully nonlinear ion-acoustic solitary waves in a plasma with positive-negative
ions and nonthermal electrons are investigated. For this purpose, the hydrodynamic …

The chemical composition of a low-pressure hydrogen dc plasma produced in a hollow
cathode discharge has been measured and modeled. The concentrations of H atoms and of …
