TLDR
In this paper, the Auger spectra in gaseous CH4, CH3Br, CH2Br2, CHBr3, CBr4, C2H6, and C6H6 are observed by means of a spherical electrostatic spectrometer at 90° to the primary electron beam.Abstract:
Auger spectra in gaseous CH4, CH3Br, CH2Br2, CHBr3, CBr4, C2H6, and C6H6 are excited by electron impact at about 5 keV energy and observed by means of a spherical electrostatic spectrometer at 90° to the primary electron beam. Besides the energies and the intensities of the Auger lines and the chemical shifts, the analysis of the spectra gives the energies and the lifetimes of the doubly ionized molecules. The line widths together with energy considerations indicate that some of these doubly ionized molecules rapidly dissociate. Comparisons are also made between the bromine and the carbon spectra.read more

Chemical‐state effects in Auger electron spectroscopy
TL;DR: In this paper, the authors used Auger spectroscopy as a probe of local chemical environment both in the gas and condensed phases using a systematically chosen series of molecules [H2O, CH3OH, (CH3)2O), CH4, C2H2, and C2C2].

Double and Triple Ionization in Molecules Induced by Electron Impact
F. H. Dorman,J. D. Morrison +1 more
TL;DR: In this paper, double and triple ionization by electron impact in molecules is examined and the data support the view that the threshold law for the probability of double ionization is a square-law function of the excess electron energy.

Absorption Cross-Sections in the Vacuum Ultra-Violet. III. Methane
TL;DR: In this paper, a cross-section for the continuous absorption of radiation by methane in the wave-length range 1600 to 350A has been measured, and the absorption is analyzed so as to distinguish between absorption leading to photo-dissociation processes and absorption due to photoionization.
