Ionization and dissociative ionization of by electron impact

Journal of Physics B: Atomic, Molecular and Optical Physics, 1997
Absolute cross sections for CO2+, C2+ and O2+ formation from CO+ by electron impact have been measured in the energy range from below the respective ionization or dissociative ionization thresholds to approximately 2500 eV. The animated crossed-beams method has been employed.

Ionization of nitromethane in the flame ionization detector

Canadian Journal of Chemistry, 1981
The mass spectra observed on sampling the unburnt gases of a flame ionization detector to which nitromethane has been added are due mostly to proton transfer reactions of NH4+ and H3O+. These are formed in the reaction zone from the primary ion HCO+, and pass through the unburnt gases to the sampling orifice.

IONIZATION AND DE-IONIZATION IN THE LOWER IONOSPHERE

1963
Abstract : A body of information pertaining to ionization and de-ionization in the lower ionosphere was compiled from various sources. Part of the data was derived from studies of geophysical observations, part of it from published and unpub lished laboratory measurements, and part from other ionospheric studies.

Total ionization and ionization fluctuations in helium

Physics Letters A, 1969
The mean energy for ion production W, the Fano factor F and some other quantities inherent to electron ionization cascades in helium are computed with semi-empirical cross sections for excitation and ionization. W = 46 eV and F = 0.21 at electron energy of 2.5 keV.

Photo-ionization of Helium and Ionized Lithium

Proceedings of the Physical Society, 1963
The work of Stewart and Wilkinson in 1960 on the photo-ionization of helium using six-parameter Hylleraas ground state and Hartree-Fock continuum wave functions has been entended to higher energies. Agreement to within 10% is obtained with the recent measurements of Baker, Bedo and Tomboulian over the spectral range 504-180 A.
