Electron impact electronic excitation of benzene: Theory and experiment
The 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.

A CALCULATION OF SEMI-EMPIRICAL ONE-ELECTRON WAVE FUNCTIONS FOR MULTI-ELECTRON ATOMS USED FOR ELEMENTARY PROCESS SIMULATION IN NONLOCAL PLASMA [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2017 Subject of Research. The paper deals with development outcomes for creation method of one-electron wave functions of complex atoms, relatively simple, symmetrical for all atom electrons and free from hard computations. The accuracy and resource intensity

Electron-impact ionization of Na
Physical Review A, 1995 Recent convergent close-coupling calculations of the ionization cross section of Na by Bray [Phys. Rev. Lett. 73, 1088 (1994)] are in poor agreement with the experimental determinations, most of which were carried out in the 1960s. We report here a measurement of the ratio of the peak ionization cross section to the cross section for excitation of the $

Impact of electron–electron cusp on configuration interaction energies [PDF]
The Journal of Chemical Physics, 2001 The effect of the electron–electron cusp on the convergence of configuration interaction (CI) wave functions is examined. By analogy with the pseudopotential approach for electron–ion interactions, an effective electron–electron interaction is developed which closely reproduces the scattering of the Coulomb interaction but is smooth and finite at zero ...

Charge Transfer Excitation of NeAr+ Ions in Collisions with Electrons
AtomsWe study the resonant processes of the excitation of weakly bound NeAr+ ions in collisions with the free electrons of Ne/Ar mixture plasma under conditions typical of the active media of gas lasers and plasma-based UV radiation sources.

Excitation of the 2S State of Atomic Hydrogen by Electron Impact
Atoms, 2018 The excitation cross sections of the 2S state of atomic hydrogen at 10 low incident electron energies (10.30 and 54.5 eV) have been calculated using the variational polarized method. Nine partial waves are used to get convergence of cross sections in the

Excitation of the 2P State of Atomic Hydrogen by Electron Impact
Atoms, 2022 The excitation cross sections of the 2P state of atomic hydrogen at low incident electron energies (from 0.755 to 3.5 Ry) were calculated using the variational polarized orbital method.

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