In this work we report calculated integral and differential elastic cross sections for the scattering of low-energy electrons by CCl4. We employ the Schwinger multichannel method with pseudopotentials to compute the cross sections in the static-exchange and static-exchange plus polarization approximations for energies up to 15 eV. We report two shape resonances located at 0.75 eV and 8 eV belonging to the T2 and E symmetries of the Td group respectively. We also look at the s-wave contribution to the integral cross section and find no evidence of the presence of a Ramsauer–Townsend minimum. We compare our calculated cross sections with available experimental and theoretical results and find that in general the agreement is good. [ABSTRACT FROM AUTHOR] |
