Computing of radiation parameters for atoms and multicharged ions within relativistic energy approach: Advanced Code

The advanced numerical atomic code based on the combined relativistic energy approach and relativistic many-body perturbation theory with the optimized zeroth ab initio model potential approximation is presented and used in computing the radiation characteristics of the multielectron atoms and multicharged ions. There are presented the results of computing the energy levels and oscillator strengths (reduced dipole matrix elements) and lifetimes for heavy alkali atom of the caesium, in particular, there are listed data for the 7s1/2 – np1/2,3/2 (n=7-10) transitions and some Ne-like multicharged ions. The comparison of the calculated values with available theoretical and experimental (compillated) data is performed. (paper)
