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.

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.
