Аннотация:The combined relativistic energy approach and relativistic many-body perturbation theory with the zeroth order optimized one-particle approximation are used for calculation of the Li-like ions (Z=11-42,69,70) energies and oscillator strengths of radiative transitions from the ground state to the low-excited and Rydberg states, in particular, 2s1/2 – np1/2,3/2, np1/2,3/2- nd3/2,5/2 (n=2-12). A comparison of the calculated oscillator strengths with available theoretical and experimental data is performed.
