Synopsis Absolute total cross sections and asymmetry parameters for photodetachment of C − ( 4 S o ) have been measured using animated-crossed-beam and velocity map imaging techniques, for photon energies from threshold up to 6eV. The cross sections are 15% to 25% larger than earlier experimental results above 2.2 eV. They are in very good agreement with those from a new R -matrix calculation using polarized pseudostates.
