Oscillator strengths for Li-like ions

Ab initio calculations including relativistic effects in the Breit-Pauli R-matrix (BPRM) method are reported for fine structure energy levels and oscillator strengths upto n=10 and 0<=l<=9 for 15 Li-like ions: C IV, N V, O VI, F VII, Ne VIII, Na IX, Mg X, Al XI, Si XII, S XIV, Ar XVI, Ca XIII, Ti XX, Cr XXII, and Ni XXVI. About one hundred bound fine structure energy levels of total angular momenta, 1/2<=J<=17/2 of even and odd parities, total orbital angular momentum, 0<=L<=9 and spin multiplicity (2S+1)=2, 4 are obtained for each ion.

The levels provide almost 900 allowed bound-bound transitions. The BPRM method enables consideration of large set of transitions with uniform accuracy compared to the best available theoretical methods. The CC eigenfunction expansion for each ion includes the lowest 17 fine structure energy levels of the core configurations ls^2^, ls2s, ls2p, ls3s, ls3p and ls3d.
