Elastic and absorption cross sections for electron-nitric oxide collisions

Abstract

In this paper, we report a theoretical study on electron scattering by an open-shell molecule in the low and intermediate energy range. More specifically, calculated elastic differential, integral and momentum transfer cross sections as well as absorption (excitation + ionization) cross sections in the 5-500 eV range are reported for e − -NO collisions. In our calculation, a complex optical potential consisting of static, exchange, correlation-polarization plus absorption contributions, derived from a fully molecular wavefunction, is used to describe the electronmolecule interaction. The Schwinger variational iterative method combined with the distortedwave approximation is applied to calculate scattering amplitudes. Comparison between calculated results and existing experimental and theoretical data is encouraging.

Elastic scattering of low-energy electrons byC3H4isomers

“…Below 15 eV the C 3 H 4 isomers can then be distinguished by their cross sections. This result is in agreement with the isomer effect ͑or isomeric effect͒, which has been pointed out by Szmytkowski and Kwitnewski,propyne,and cyclopropene at 5,7,10,12,15,20,25, and 30 eV. The calculated DCS for allene and propyne are compared with the results of Nakano et al In both cases our calculated DCS agree very well with experiment, except at 5 and 7 eV.…”

Elastic and rotational excitation cross sections for electron–nitrous oxide collisions

“…Recently, we applied an optical potential formed by exact SE and model correlation‐polarization contributions to study electron–molecule scattering in the low and intermediate energy range 22–26. In general, the calculated results in those studies are in good agreement when compared with available experimental data.…”

Ionization of P Atom, P\(_2\) and PX (X = H, C, N, O) Molecules by Electron Impact: Theoretical Studies

“…The spherically averaged atomic and molecular charge density ρ(r) is determined from the constituent atomic charge densities derived from the atomic wave functions of [11]. Now, the imaginary term V I of the complex potential, also called the absorption potential V abs is adopted here in a well-known non-empirical quasi-free model form given by Staszeweska et al [11] (see also [12], [13]). Thus,…”

“…The dynamic functions A 1 , A 2 and A 3 occurring in the equation (4) are specific functions of the quantities ρ(r), I, ∆ and E i . Detailed expressions of these functions are given in [11] and also in [12,13].…”
