Abstract
Theoretical and normalized experimental differential, momentum transfer, and integral cross sections for vibrationally elastic scattering of low-energy electrons from toluene $({\mathrm{C}}_{6}{\mathrm{H}}_{5}\mathrm{C}{\mathrm{H}}_{3})$ are presented. The differential cross sections are measured at incident energies from 1 to 20 eV and scattering angles from 15\ifmmode^\circ\else\textdegree\fi{} to 130\ifmmode^\circ\else\textdegree\fi{}. The calculated cross sections are obtained using the Schwinger multichannel method with pseudopotentials in the static-exchange plus polarization approximation. Comparisons are made between the present theory and measurements with earlier available measurements. In general, the agreement between the theory and the experiment is very good. We also discuss the resonance spectra of toluene, where we find three \ensuremath{\pi}* shape resonances whose locations agree well with the experiment. In addition, we compare the cross sections of toluene and benzene, since the former can be considered as a benzene derivative by the substitution of a hydrogen in benzene by a $\mathrm{C}{\mathrm{H}}_{3}$ group in toluene.
