Dh. Lee et al., CROSS-SECTION FOR PHOTODETACHMENT OF THE EXCITED C-(D-2) ION USING FAST ION-LASER-BEAM ELECTRON-SPECTROSCOPY, Physical review. A, 56(2), 1997, pp. 1346-1350
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).
