This paper describes the measurement of charge transfer cross-sections for protons, molecular hydrogen ions and helium ions in the rare gases and hydrogen, and electron detachment cross-sections for negative atomic hydrogen ions in the rare gases. Part I describes the energy range 3 to 40 keV. In part II the energy range 100 to 4000 eV is described, and the results are discussed in terms of the pseudo-adiabatic hypothesis. Comparisons are made with other experimental results, and anomalous molecular cases are discussed in terms of reactions involving anti-bonding states.

The influence of metal hydride hollow cathode on a Penning ion source operation has been carried out. The feature of investigation is hydrogen injection only due to its desorption from metal hydride under ion-stimulated processes. The regimes of optimal discharge operation in the hollow cathode mode are determined. It has been revealed that the transition to the hollow cathode mode occurs at lower voltages, the discharge works without external gas supply, and the working pressure in the cell is set at the level determined by the discharge current. The supply of a negative bias to the metal hydride hollow cathode weakly affects the features of the emission of axial particles, although it allows the increase of plasma density near the metal hydride hollow cathode.

ABSTRACTComposite nanowires with typical diameters of 30-100nm, which consisted of Si, β-SiC, amorphous carbon were converted from Si nanowires by ion beam deposition. The Si nanorods were exposed to broad low energy ion beams. The low energy hydrocarbon, argon and hydrogen ions, generated in a Kaufman ion source, reacted with Si nanowires and formed the composite nanowires. It has been assumed that the reaction pathway to form the composite nanowires were driven by both thermal diffusion and kinetic energic of interacting particles.

Detailed experiments on the energy and angular distributions of both electrons and protons formed from molecular hydrogen in strong femtosecond laser fields are reported. At the wavelengths 389 and 406 nm the ionization dynamics is governed by resonance shifting of molecular Rydberg states. Differences from this mechanism appear only at the very lowest intensities, when close lying resonances of the E, F-state determine the photoelectron pattern in resonant enhanced ionization, and at very high intensities, when tunnel ionization suppresses molecular details. At wavelengths below 400 nm at intensities in the range of ≈1·1013 W/cm2 femtosecond pulses are quite suitable for preparation of state selected H2+ targets in a restricted range of vibrational levels.
