摘要：

In this paper, we present the first absolute measurements for photoionization of multiply charged oxygen ions: O2+ and O3+ in the ground state and in several metastable states, as well as relative data for O4+. Multi-configuration Dirac-Fock and relativistic R-matrix calculations were performed and are tested here by comparison with experimental results. Our experimental and new theoretical results are also compared with the earlier theoretical data obtained in the R-matrix approximation to calculate photoionization cross sections over part of the isonuclear series of multiply charged oxygen ions.
