Electron impact electronic excitation of benzene: Theory and experiment

open access: yesThe Journal of Chemical Physics, 2023
We report experimental differential cross sections (DCSs) for electron impact excitation of bands I to V of benzene at incident energies of 10, 12.5, 15, and 20 eV. They are compared to calculations using the Schwinger multichannel method while accounting for up to 437 open channels.

Atomic Lithium Excitation by Electron Impact

open access: yesJournal of Kufa-Physics, 2019
Bethe approximation had been used to compute the excitation cross section in term of the diploe oscillator strength for some allowed transitions between energy levels of Li-atom collide with electrons with impact energy range (2-2000) eV. We also compute

Electron Impact Excitation of F-Like W LXVI

open access: yesAtoms, 2016
Electron impact excitation collision strengths are calculated for all transitions among 113 levels of the 2s 2 2p 5 , 2s2p 6 , 2s 2 2p 4 3ℓ, 2s2p 5 3ℓ, and 2p 6 3ℓ configurations of F-like W LXVI. For this

Electron-impact excitation of neutral boron using the R-matrix with pseudostates method [PDF]

open access: yes, 1989
We have carried out a large R-matrix with pseudostates (RMPS) calculation of the electron-impact excitation of neutral boron. The RMPS method has been employed for the excitation/ionisation of many light fusion related species, but primarily for one or ...

R-Matrix Scattering Calculations for Iron-Peak Species: Photoionisation of Fe I and Electron-Impact Excitation of Fe II

open access: yesGalaxies, 2018
An abundance of absorption and emission lines of iron-peak species such as Fe I and Fe II can be seen in the spectra of many astrophysical objects. Thus, the accurate modelling of such spectra requires sets of high quality atomic data for these species ...

Electronic excitation of CH4 by low-energy electron impact [PDF]

open access: yesThe Journal of Chemical Physics, 1993
We report cross sections for excitation of the (1t2→3sa1) singlet and triplet states of methane by low-energy electron impact. The cross sections for these dissociative states were obtained using the Schwinger multichannel variational method with up to seven channels (three physical states) coupled.
