摘要: The dipole-length, dipole-velocity and dipole-acceleration absorption oscillator strengths for the 1s22s--1s2np (3 ≤ n ≤ 9) transitions of lithium-like systems from Z=11 to 20 are calculated by using the energies and the multiconfiguration interaction wave functions obtained from a full core plus correlation method, in which relativistic and mass-polarization effects on the energy, as the first-order perturbation corrections, are included. The results of three forms are in good agreement with each other, and closely agree with the experimental data available in the literature. Based on the quantum defects obtained with quantum defect theory (QDT), the discrete oscillator strengths for the transitions from the ground state to highly excited states 1s2np (n ≥ 10) and oscillator strength densities corresponding to the bound-free transitions are obtained for these ions.
