摘要：
In this paper we present integral and differential cross sections for electron scattering by the C3H4 isomers allene and propyne for energies from 1 to 10 eV. To compute the scattering cross sections we employ the Schwinger multichannel method with pseudopotential at the static exchange plus polarization approximation. Our results are in good agreement with experimental total cross sections and differential cross sections. We also discuss the role of the isomer effect in the cross sections of these isomers in the 1-10 eV energy range.
