内容記述 | Energy levels, radiative transition probabilities, and autoionization rates for C-like oxygen (O^2+) including 1s^2 2s^2 2pnl, 1s^2 2s2p^2 nl, and 1s^2 2p^3 nl (n=2-8, l leq n - 1) states are calculated by the Hartree-Fock-Relativistic method (Cowan code). Autoionizing levels above the thresholds1s^2 2 s^2 p 2^P, 1s^2 2s2p^2 4^P, ^2 D, ^2S; ^2P, and 1s^2 2p^3 ^4S; ^2D are considered. Configuration mixing 2s^2 2pnl + 2p^3nl plays an important role for all atomic characteristics. Branching ratios relative to the first threshold and intensity factors are calculated for satellites lines, and dielectronic recombination rate coefficients are presented for the excited 218 odd-parity and 218 even-parity states. The dielectronic recombination (DR) rate coefficients are calculated including 1s^2 2s^2 2pnl, 1s^2 2s2p^2 nl, and 1s^2 2p^3nl (n=2-8, l leq n -1) states. Contributions from the excited states with n leq 8 are estimated by extrapolation of all atomic characteristics to derive the total DR rate coe cient. It is found that the orbital angular momentum quantum number l distribution of the rate coefficients shows a peak at l=4. The total DR rate coe cient is derived as a function of electron temperature. The state-selective DR rate coe cients to excited states of C-like oxygen, which are useful for modeling O III spectral lines in a recombining plasma, are calculated as well. | |||||
