| 英文摘要 | Wavefunctions were determined using the multi-configuration dirac-hartree-fock method. the core-core, core-valence, valence correlation, breit interaction and quantum electrodynamics effects, as well as some higher-order correlation effects, were considered to obtain accurate wavelengths (lambda), oscillator strengths (gf) and transition rates (a) of 2s(2)2p(2) - 2s2p(3), 2s2p(3) - 2s(2)2pnl (n >= 3) and 2s2p(3) - 2s2p(2)3s e1 transitions. the branching ratio of 2s2p(3) s-5(2)o (namely a(lambda 2143.45)/a(lambda 2139.68)) based on the latest calculation of 2.462 +/- 0.119 is recommended for the determination of a nebula's electron temperature and electron density. the largest calculated gf value of 2s2p(3) -2s(2)2p4p is lambda 630.65, differing from that of lambda 1060.2 (i.e. 2s2p(3) p-3(2)o - 2s(2)2p4p s-3(1)) that was observed with the largest intensities in the orion nebula spectrum. in addition, the energy levels and the splittings of 2s2p(3), the extremely difficult calculations of the rates of two-electron one-photon transitions as well as those of the very small intercombination a of 2s2p(3) s-5(2)o were studied in detail. because of the weak spin-orbit interaction, accurately calculating the levels p-3(1,2,0)o (or d-3(3,2,1)o) and their transition matrix elements is very sensitive to relativistic and electron correlation effects. a special case for this is when the transition operators synchronously applied to wavefunctions with regard to 2s2p(3) p-3(o) and 2s(2)2pnl (n = 4) become extremely sensitive to some higher-order correlation effects. |
