Electron-Impact Ionization Cross Sections of Atmospheric Molecules
A theoretical model for electron-impact total ionization cross sections, which has been found to be reliable for a wide range of molecules, is applied to molecules of interest to atmospheric science. The new theory, the binary-encounter-Bethe (BEB) model, combines the binaryencounter theory and the Bethe theory for electron-impact ionization, and uses simple theoretical data for the ground stat...
متن کاملElectron impact dissociation cross sections for C2F6
Absolute total dissociation cross sections for electron impact, σt,diss, from 8 to 700 eV are reported for C2F6. A dense set of data was obtained in the technologically important 8–30 eV energy range relevant to modelling the type of plasmas used in both fundamental and applied scientific investigations. The threshold for dissociation was found to be 12.0 ± 0.2 eV and appears to be associated w...
متن کاملNew Model for Electron-Impact Ionization Cross Sections of Molecules
A theoretical model for electron-impact ionization cross sections, which has been developed primarily for atoms and atomic ions, is applied to neutral molecules. The new model combines the binary-encounter theory and the Bethe theory for electron-impact ionization, and uses minimal theoretical data for the ground state of the target molecule, which are readily available from public-domain molec...
متن کاملDifferential cross sections for the electron impact excitation of pyrimidine.
We report on differential cross section (DCS) measurements for the electron-impact excitation of the electronic states of pyrimidine. The energy range of the present measurements was 15-50 eV with the angular range of the measurements being 10°-90°. All measured DCSs displayed forward-peaked angular distributions, consistent with the relatively large magnitudes for the dipole moment and dipole ...
متن کاملElectron impact excitation cross sections for carbon monoxide
We present distorted-wave cross sections for excitation of the A 'TI, a k, a' '2+, D 'A and d 3A states of CO by electrons in the 20 to 50 eV energy range. In these studies both the initial and final distorted waves are obtained in the static-exchange field of the ground electronic state. Differential and integral cross sections are presented and compared with available experimental data and wi...
