Despite the importance of BCl3 in plasmas used for commercial etching processes, no calculations or measurements of elastic low-energy electron scattering from BCl3 have previously appeared in the literature. We therefore present calculations based on the complex Kohn method for elastic electron-BCl3 scattering at incident electron energies below 8 eV. We find a near-zero-energy virtual state and a sharp temporary negative-ion resonance at 0.25 eV, which likely contributes to the large electron attachment cross sections observed in swarm studies.
