Elastic electron scattering from chlorobenzene

Abstract

We report a joint theoretical–experimental investigation on elastic electron scattering by chlorobenzene in the low- and intermediate-energy ranges as a part of a collaborative project established between the Federal University of São Carlos (UFSCar) and the California State University (CSUF). More specifically, experimental elastic differential cross sections (DCS), in the incident electron energy range of 1.0 to 800 eV and scattering angle range of 10° to 130°, were measured using the crossed-beam relative-flow technique. Integral and momentum-transfer cross sections were determined from the numerical integration over the experimental DCS. Theoretically, elastic differential, integral, and momentum-transfer cross sections were calculated using a combination of a molecular complex optical potential model with the Padé approximant technique for impact energies ranging from 1.0 to 150 eV. Further calculations of DCS were performed at an energy range of 20 to 500 eV using the independent-atom model. Our results, which significantly extend available electron scattering cross sections for this target, are compared to existing theoretical and experimental data in the literature.

Collisions of low- to intermediate-energy electrons with acetonitrile

“…The inclusion of higher partial waves was accomplished in the same manner as mentioned in [37,38]. The codes for this task were not originally implemented in ePSE3, but this was already made in another suite that we have extensively used in previous works of our group [37][38][39][40][41][42][43][44][45].…”
