Abstract
A crossed-beam apparatus incorporating photoelectron spectroscopy has been used to determine the partial cross section for photodetaching an electron from the excited C-(D-2) ion via the (3)Pks,d channels. The measurement, which was based on the saturation of the photodetachment process, was normalized to that of D- taken under the same experimenta l conditions. At a photon energy of 2.076 eV, the cross section was fo und to be 13(2) Mb. Simultaneously, the beam fraction in the excited s tate in the incoming C- ion beam was found to be 0.5(1).
