Abstract

Configuration interaction calculations of oscillator strengths, transition probabilities, and lifetimes for transitions between levels belonging to calcium-like titanium (Ti III) have been executed using CIV3 code. A set of configuration state list of 220-configuration and correlations up to 6 l orbitals have been included in the calculations. The relativistic effects i.e, the Breit-Pauli Hamiltonian terms, such as the one body mass correction and Darwin term, and spin-orbit, spin-other-orbit, and spin-spin corrections, are included in the calculations. The present calculations of oscillator strengths are in good agreement with the published experimental and theoretical values.
