Abstract
We have investigated valence-shell photoionization (PI) of S-1 ground state and P-3(o) metastable states of C2+ ions. Absolute PI cross-sections were measured in the range 40.7-56.4 eV with an energy spread of 30 meV using a photon-ion merged beams arrangement at the Advanced Light Source (ALS). Detailed calculations based on the semi-relativistic Breit-Pauli R-matrix approach suggest a fraction of 40% of metastable ions in the primary beam of the experiment. Additional high resolution measurements have been carried out with an energy spread as low as 7.5 meV. The new data permit a sensitive test of theory with respect to the individual PI cross-section contributions originating from the different P-3(0.1.2) fine-structure components of the initial triplet states.
