【Abstract】 The transition energies and oscillator strengths of 1s²2p¹s²nd （3 ≤n≤ 9） for lithium-like Ti⁺¹⁹ ion are calculated by using a full core plus correlation method. The fine structure splittings of 1s²np and 1s²nd（n≤9） states are also evaluated. The quantum defects of these two Rydberg series are determined. The values of oscillator strength obtained from three formulae agree closely with each other. Combining the discrete oscillator strengths with the single channel quantum defect theory, the discrete oscillator strengths for the transitions from 1s²2p state to highly excited states 1s²nd（n≥10） and oscillator strength densities corresponding to the bound-free transitions are obtained for this ion.更多还原
