Abstract
Energy levels, wavelengths, oscillator strengths, transition probabilities, line strengths, and lifetimes are calculated for transitions in Ti XIV. The 2s22p5, 2s2p6, 2s22p43l, 2s2p53l, 2p63l, 2s22p44l, and 2s2p54l (l = s, p, d) configurations are used in the calculations and 218 fine-structure levels are obtained using the general-purpose relativistic atomic structure package (GRASP). The results for the electric dipole, electric quadrupole, magnetic dipole, and magnetic quadrupole transitions from the levels of the 2s22p5, 2s2p6, 2s22p43l, 2s2p53l, and 2p63l (l = s, p, d) configurations to the levels of 2s22p5 and 2s2p6 configurations are presented. Comparisons are made with the available experimental and the other calculations.
