OSCILLATOR-STRENGTHS FOR TRANSITIONS IN C-LIKE NE, MG, SI, AND S IONS

Energy levels and oscillator strengths (transition rates) have been ca lculated for the fine-structure transitions among the levels of the (1 s(2)) 2S(2)2p(2), 2s2p(3), 2p(4), 2s(2)2p3s, 2s(2)2p3p, and 2s(2)2p3d configurations of C-like Ne V, Mg VII, Si IX, and S XI ions using the CIV3 program. The extensive configuration interaction and relativistic effects have been included while generating the wave functions. The r esults are compared with other available theoretical values. The diffe rences among the various calculations are discussed and the accuracy o f the results is assessed.
