“…In Figure 2(a-f), we present our DCS calculations for electron scattering at 70, 75, 90, 100, 150 and 200 eV and compare with the experimental data [9][10][11][12]14] and theoretical calculations [3,30,32,33]. Our calculations show quite good agreement with the experimental measurements.…”

“…Here, R p is the value of R at E i = E p with E p being the incident energy at which the maximum absorption occurs. The present study observes the maximum absorption at E p = 60 eV [30], Jain et al [3] and Wedde and Strand [33]. Experimental: Shyn and Carignan [9], Srivastava et al [10], Nickel et al [14] and DuBois and Rudd [11].…”

“…Blanco and Garcia [32] published their calculations on DCS, TCS and IECS (10-10,000 eV) for e − −N 2 scattering using the independent atom model (IAM). Wedde and Strand [33] reported calculations on DCS (20-90 eV) using the phase-amplitude method. Phelps and Pitchford [34] calculated IECS, INCS, MTCS, TICS and TCS for electron energies from 0.003 to 10 keV with use of the multiterm spherical-harmonic expansion solution of the Boltzmann equation.…”

Scattering of e^± from N₂ in the energy range 1 eV–10 keV

The differential, integrated elastic, inelastic, total, momentum transfer, viscosity, and ionisation cross sections for electron and positron scattering from the homonuclear diatomic nitrogen molecule over an incident energy range of 1 eV-10 keV are calculated using the additivity rule. Dirac partial wave analysis is employed to calculate the cross sections of the constituent atoms of molecules, using a complex optical model potential (OPM). Comparison of our results of the additivity rule with the available experimental data and other theoretical predictions is presented. Our findings produce reasonable results in intermediate and high energies.

“…A simple formula for the true backscatter ratio is derived for electrons that scatter according to a screened Rutherford cross section (i.e., applicable to energies greater than about 1 keV). It is conjectured that this formula, which involves only the screening parameter, may also be used for energies less than 1 keV if the screening parameter is determined from appropriate low-energy data such as those of Wedde and Strand [1974].…”

An explicit solution to the electron transport and energy degradation problem is presented in the two‐stream approximation. The validity of this simple approach is discussed, and it is shown that it can be extended to high electron energies (appropriate for applications to auroras) provided the coupling between the two streams, described by the backscatter ratio, is correctly estimated. A simple formula for the backscatter ratio which can be used at all energies is derived.
