Popis:	A 25-state R-matrix calculation is performed to obtain photoionization cross-sections for transitions from the 1s 2 2s 2 2p 2 3 P ground state of the O III ion. Results are obtained for a range of photon energies, includingthose at which K-shell photoionization processes take place. We compare our results with those from previous calculations. Excellent agreement is obtained. We also consider resonances owing to transitions of a 1s electron excited into the 2p orbital and compare with a recent calculation.
