A large-scale configuration interaction (CI) calculations are performed to evaluate the energy levels, oscillator strengths and transition probabilities for all the transitions from the ground-state level to those of 3s3p2, 3s2 nl (nl = 3d,4s,4p,4d,4f,5s,5d,6d,6f), 3s3pnl(nl = 3d,4s), 3s3d2 and 3p3 states of Ti X in LSJ coupling scheme. Lifetimes of the excited levels are also determined. The calculations include the major correlation effects. The relativistic effects are incorporated by adding mass correction, Darwin term and spin-orbit interaction terms to the non-relativistic Hamiltonian in the Breit-Pauli approximations. The calculated energy levels are in close agreement with the NIST results. We have predicted many new spectral lines, which are to be experimentally observed in future.
