Ionization and dissociative ionization of methane molecules

Technical Physics, 2013
A technique for mass-spectrometric investigation of the yield of positive ions produced by direct and electron-impact dissociative ionization of methane molecules is described, and respective experimental data are presented. Doubly charged C 2 + , CH 3 2+

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.

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.
