Oscillator strengths for transitions in C-like ions between FIV and Ar XIII

Energy levels and oscillator strengths (transition probabilities) have been calculated for the fine-structure transitions among the levels of the (1s( 2)) 2s(2)2p(2), 2s2p(3), 2p(4), 2s(2)2p3s, 2s(2)2p3p, and 2s(2)2p3d configu rations of C-like F IV, Na VI, Al VIII, P X, Cl XII, and Ar XIII using the CIV3 program. The extensive configuration interaction and relativistic effe cts have been included while generating the wavefunctions. Calculated value s of energy levels generally agree within 5% with the experimentally compil ed results, and the length and velocity forms of oscillator strengths agree within 20% for a majority of allowed transitions.
