A crossed-beam apparatus incorporating photoelectron spectroscopy has been used to determine the partial cross section for photodetaching an electron from the excited C{sup {minus}}({sup 2}D) ion via the {sup 3}Pks,d channels. The measurement, which was based on the saturation of the photodetachment process, was normalized to that of D{sup {minus}} taken under the same experimental conditions. At a photon energy of 2.076 eV, the cross section was found to be 13(2) Mb. Simultaneously, the beam fraction in the excited state in the incoming C{sup {minus}} ion beam was found to be 0.5(1). {copyright} {ital 1997} {ital The American Physical Society}
