We report the integral elastic cross section for low-energy electron scattering by CS2 molecules. To perform our calculations we used the Schwinger multichannel method with pseudopotentials.We have found, in a static-exchange calculation, a shape resonance around 1 eV that belongs to the Π u symmetry.With the inclusion of polarisation effects only in that symmetry, we show that the resonance becomes a bound state. This result is in agreement with other results available in the literature.
