Abstract
This paper presents calculations of the oscillator strengths and A-values between the 3p6ns 2Se (J = 1/2) (n = 4 to 10) states of Ti IV and the 3p6mp 2Pe (J = 1/2 and 3/2) (m = 4 to 10) states. The calculations were carried out using configuration interaction wave functions in which relativistic effects were included by using the Breit–Pauli approximation. To obtain an indication of the accuracy of the oscillator strengths, calculations were carried out using both the length and velocity formulations of the oscillator strengths. These calculations improve on the accuracy of the earlier work on the excitation of the 3p64s 2S excited state of Ti IV to the 3p6mp 2Po excited states (Kingston and Hibbert 2008 J. Phys. B: At. Mol. Opt. Phys. 41 155001) by increasing the number of configurations in the calculations. Comparisons of the present calculations are made with other theoretical calculations.
