Radiative transitions from singly ionized oxygen

 Fully relativistic calculations have been performed on the states of 2p3,2p23s,2p23pand2p2(3P)3d configurations of singly ionized oxygen. The calculations have been carried out using multi-configuration Dirac-Fock wavefunctions with the inclusion of Breit interaction and quantum electrodynamic contributions. A substantial amount of correlation has also been included in our calculations. The numerical results for more than 150 electric dipole lines in the spectrum of O+ are compared with other theoretical and experimental values.
