Abstract: 

Absolute cross sections for the K-shell photoionization of ground-state Li-like carbon [C3+(1s(2)2s(2)S)] ions were measured by employing the ion-photon merged-beams technique at the Advanced Light Source. The energy ranges 299.8-300.15 eV, 303.29-303.58 eV and 335.61-337.57 eV of the [1s(2s2p)P-3]P-2, [1s(2s2p)P-1]P-2 and [(1s2s)S-3 3p]P-2 resonances, respectively, were investigated using resolving powers of up to 6000. The autoionization linewidth of the [1s(2s2p)P-1]P-2 resonance was measured to be 27 +/- 5meV and compares favourably with a theoretical result of 26 meV obtained from the intermediate coupling R-matrix method. The present photoionization cross section results are compared with the outcome from photorecombination measurements by employing the principle of detailed balance.
