The R-matrix method is used to calculate low-energy electron scattering and dissociative attachment cross sections for HCl. Nuclear vibration is included using a non-adiabatic approximation. Two models, differing only in their treatment of polarisation effects, are used. At energies below the v=2 threshold, the cross sections are found to be very sensitive to these effects. The peaks in the vibrational excitation cross sections are seen to correspond to resonance poles in the S matrix and can therefore be interpreted as nuclear excited Feshbach resonances.
