OPTIMIZED RELATIVISTIC MODEL POTENTIAL METHOD AND QUANTUM DEFECT APPROXIMATION IN THEORY OF RADIATIVE TRANSITIONS IN SPECTRA OF MULTICHARGED IONS

Т. Б. Ткач

Анотація


The combined relativistic model potential approach and relativistic many-body perturbation theory with the zeroth order optimized one-particle approximation are used for calculation of the Li-like ions energies and oscillator strengths of radiative transitions from ground state to low-excited and Rydberg states. New element in our scheme is an implementation of optimized relativistic model potential and quantum defect approximation) approach to energy approach frames. Comparison of calculated oscillator strengths with available theoretical and experimental (compillated) data is performed.
