The elastic scattering of slow electrons by carbon

Phase shifts, partial cross sections and total cross section for the elastic scattering of slow electrons by carbon are calculated in the static central field exchange approximation. The scattering length is 1.85 α 0 and the zero energy cross section is 13.69πα 0 2 . A resonance in the p-wave scattering is predicted at 0.605 ryd, in the neighbourhood of the first excited state of carbon, and a Ramsauer minimum at 0.71 ryd.
