Electron impact scattering by SF₆ molecule over an extensive energy range

Abstract

Theoretical elastic and inelastic cross sections for e-SF6 scattering over 0.1–5000 eV energies are reported employing R-matrix and SCOP formalisms.

Electron induced ionisation of C3 to C6 ethanoates

“…Therefore, for each scattering centre the independent inelastic contributions are calculated separately using the single centre SCOP formalism. [11][12][13][14][15][16][17] Then, the total inelastic cross-section for the molecule was obtained by adding the contribution from each centre. The total ionisation cross-section was then evaluated from the total inelastic cross-section by the semi-empirical CSP-ic method.…”

“…Therefore, the electron impact total ionisation crosssection for these molecules over such a wide energy range (11-5000 eV) is presented for the rst time. The spherical complex optical potential (SCOP) method [11][12][13][14][15][16][17] and group additivity rule (GAR) 11 were employed to calculate the total inelastic cross sections for the ethanoates. A semi-empirical approach called complex scattering potential-ionisation contribution (CSP-ic) method [11][12][13][14][15][16][17] was used to deduce the total ionisation cross-section of the molecules.…”

Electron scattering from germanium tetrafluoride

“…The low energy computations were carried out using the ab initio R-matrix method 8 through Quantemol-N package. 9 The spherical complex optical potential (SCOP) [10][11][12][13] formalism is employed for the high energy calculations. The ab initio Rmatrix method is suitable for low energies typically below the ionization threshold of the target, whereas SCOP formalism provides satisfactory results for energies above the ionization threshold to 5 keV.…”

Brief Review of Electron Collision Studies of Molecules Relevant to Plasma

“…Goswami and Antony [64] have recently calculated cross-section for elastic and inelastic processes for an extensive range of energies for SF 6 using the R-matrix and spherical complex optical potential (SCOP) [32,33] methods. They have provided detailed references for various cross-section studies on SF 6 in their article; hence, readers are directed to their article for more information about SF 6 .…”
