| Abstract: | The relative cross section has been measured in the threshold regions of the following transitions: C?(4S) + hv → C3P0,1,2) + e? and C?(2D) + hv → C(1D) + e?. The electron affinity of carbon is determined EA(C) = 1.2629 ± = 0.0003 eV, and the binding energy of the metastable C?(2D) state with respect to the C(3P0) ground state is 0.033 ± 0.001 eV. |
