Abstract
In this paper we report integral and differential cross sections for the elastic scattering of low-energy electrons by C4H8 isomers, namely 1-butene and 2-methylpropene. The scattering cross sections were obtained using the Schwinger multichannel method with pseudopotentials, in the static-exchange and in the static-exchange plus polarization approximations, for energies of the incident electron ranging from 0.5 eV to 15 eV. Our calculations indicate that the 1-butene molecule has a resonance in the A″ symmetry at around 2.1 eV, in agreement with the experimental data of 2.3 eV as reported by Mozejko et al (2012 J. Phys. B 45 145203). The 2-methylpropene molecule has a resonance in the B2 symmetry, located at around 2.8 eV and also in good agreement with the experimental results of Mozejko et al around 2.4 eV. We also report differential cross sections around the energy of the broad structure present in the integral cross sections of both molecules, and discuss their oscillatory behavior in terms of the type of the molecular chain.
