This work is an ab initio study of the 2p{sup 3} {sup 4}S{sub 3/2}{sup o}, and {sup 2}D{sub 3/2,5/2}{sup o} states of C{sup -} and 2p{sup 2} {sup 3}P{sub 0,1,2}, {sup 1}D{sub 2}, and {sup 1}S{sub 0} states of neutral carbon. We use the multiconfiguration Hartree-Fock approach, focusing on the accuracy of the wave function itself. We obtain all C{sup -} detachment thresholds, including correlation effects to about 0.5%. Isotope shifts and hyperfine structures are calculated. The achieved accuracy of the latter is of the order of 0.1 MHz. Intraconfiguration transition probabilities are also estimated.
