  Ab initio calculations including relativistic effects employing the
Breit-Pauli R-matrix (BPRM) method are reported for fine structure energy
levels and oscillator strengths upto n = 10 and 0.leq. l .leq.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 .leq. J .leq. 17/2 of
even and odd parities, total orbital angular momentum, 0 .leq L .leq. 9 and
spin multiplicity (2S+1) = 2, 4 are considered for each ion. The levels provide
almost 900 dipole allowed and intercombination 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 1s^2, 1s2s, 1s2p, 1s3s, 1s3p, and
1s3d. The calculated energies of the ions agree with the measured values to
within 1% for most levels. The transition probabilities show good agreement
with the best available calculated values. The results provide the largest sets
of energy levels and transition rates for the ions and are expected to be
useful in the analysis of X-ray and EUV spectra from astrophysical sources.
