Electron impact excitations of S2 molecules
Low-energy electron impact excitations of S2 molecules are studied using the fixedbond R-matrix method based on state-averaged complete active space SCF orbitals. Integral cross sections are calculated for elastic electron collision as well as impact excitation of the 7 lowest excited electronic states. Also, differential cross sections are obtained for elastic collision and excitation of the a...
متن کاملElectron - Impact Excitation of Interstellar Molecules
Electron-molecule collisions play a crucial role in astrophysical environments where the electron fraction is higher than about 10−5, e.g. in the diffuse ISM, PDRs or comets. We present here a brief review of our recent R-matrix calculations of rate coefficients for electron-impact rotational excitation of interstellar molecules. Our major result is the prediction of emission lines from higher ...
متن کاملElectron-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 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 کاملElectron-Impact Cross Sections for Ground State to np Excitations of Sodium and Potassium
Cross sections for electron impact excitation of atoms are important for modeling of low temperature plasmas and gases. While there are many experimental and theoretical results for excitation to the first excited states, little information is available for excitation to higher states. We present here calculations of excitations from the ground state to the np levels of sodium (n = 3 through 11...
