Penning ionization cross sections and rate constants

Electron Ionization Cross Sections of PF3 Molecule

Partial single and double differential cross sections with their sums through direct and dissociative ionization of PF3 have been evaluated at fixed electron energies 100 and 200 eV, by using modified Jain-Khare semi-empirical approach. To the best of my knowledge no other data of differential cross sections are available for the comparison. I have also calculated integral ionization cross sect...

Resonant vibrational-excitation cross sections and rate constants for low-energy electron scattering by molecular oxygen

Resonant vibrational-excitation cross sections and rate constants for electron scattering by molecular oxygen are presented. Transitions between all 42 vibrational levels of O 2 (X 3 − g) are considered. Molecular rotations are parametrized by the rotational quantum number J , which is considered in the range 1–151. The lowest four resonant states of O − 2 , 2 g , 2 u , 4 − u and 2 − u are take...

Formulae for cross sections and rate coefficients

Robust, accurate and asymptotically exact cross section formulae for all direct and dissociative electron impact ionization channels of methane and hydrogen are presented. The parameter estimation employs Bayesian inference and allows for a consistent use of data from different experiments with possibly discordant calibrations. An efficient method for the calculation of rate coefficients and th...

Electron-Impact Total Ionization Cross Sections of CH and C2H2

Electron-impact total ionization cross sections for the CH radical and C2H2 (acetylene) have been calculated using the Binary-Encounter-Bethe (BEB) model. The BEB model combines the Mott cross section and the asymptotic form of the Bethe theory, and has been shown to generate reliable ionization cross sections for a large variety of molecules. The BEB cross sections for CH and C2H2 are in good ...
