Photodetachment of the outer shells of the excited {sup 2}D state of C{sup -} using an augmented R-matrix theoretical methodology has been studied from threshold to 11 eV. Total and partial cross sections and photoelectron angular distribution asymmetry parameters have been obtained. Excellent agreement between length and velocity formulations is found. In addition, agreement with experiment at 2.076 eV for both cross section and {beta} for photodetachment to the ground 2s{sup 2}2p{sup 2} {sup 3}P state of C is quite good. The results exhibit many examples of Auger decay of shape resonances. Comparison with a previous calculation shows fair agreement except near threshold.
