A crossed-beam apparatus has been employed in a spectroscopic study of electrons photodetached from C − ions at a photon energy of 2.08 eV. Measurements of the partial cross sections σ and asymmetry parameters β for the hν + C − ( 2 D) → C( 1 D) + e − (ks, d) and hν + C − ( 4 S) → C( 3 P) + e − (ks, d) processes yielded the following results: σ ( 2 D-1 D) = 5(2) Mb, σ ( 4 S-3 P) = 12(3) Mb and β( 2 D-1 D) = −0.93(7), β( 2 D-1 D) = −0.88(7). These are the first measurements in the case of the 2 D-1 D transition.
