Abstract
The energy spectra as well as the electric quadrupole (E2) and the mag netic dipole (M1) transitions in the oxygen isoelectronic sequence bet ween the levels of the Is(2)2s(2)2p4, 1s(2)s2p5 and 1s(2)2p6 configura tions were considered. The stationary second-order many-body perturbat ion theory (MBPT) was used to account for electron correlations. The r elativistic corrections were included in the Breit-Pauli approximation .
