Elastic scattering of low-energy electrons by carbon disulphide

Abstract: We report results from an ab initio calculation of low-energy electron scattering by C S 2 molecules using the Schwinger multichannel method with pseudopotentials. We calculated elastic integral, di erential and momentum transfer cross sections in an energy range from 5 eV up to 50 eV and compared our results with available theoretical results and experimental data. Through the symmetry decomposition of our integral cross section and eigenphase sum analysis, we found cross section peaks that may b e i n terpre… Show more

“…Our Q e agrees well with the previous result of Sohn et al 27 below 5 eV, but no other experimental data are available for comparison from 8 to 200 eV. Six theoretical approaches are available for comparison, those of Lynch et al, 31 Lee et al, 41 Bettega et al, 42,43 Gianturco and Stoecklin, 44 and Raj and Tomar, 30 as well as the present IAM-SCAR calculation. The calculation of Raj and Tomar 30 (only above 100 eV) considerably overestimates the experimental measurement.…”

“…At 5 eV ( Figure 5(b)) the agreement with Sohn et al 27 is again very good, although some small differences in magnitude occur for scattering at mid angles (∼60 • ). As at lower energies, the IAM-SCAR, SMC 42,43 and SVIM 41 theories provide good agreement with experiment in different angular ranges, with the SVIM calculation in better agreement at angles below 60 • , while the IAM-SCAR result agrees better at larger angles. At 20 eV ( Figure 5(c)) all five calculations agree with experiment very well for angles less than 60 • .…”

“…This database covers the 50 eV-100 MeV range. For electrons with energy smaller than 50 eV, the elastic cross-sections calculated by Bettega et al for CS 2 [43] are used, following the recommendation and justification given by Akkerman et al in [16]. The lowest energy considered by Bettega is 5 eV; the model is thus applicable for the entire range of electron energies considered in this work.…”
