“…This is in line with earlier prediction [16] that in high-Z atoms the effect of the SO processes on the cascade decays of vacancies is expected to be small since most of the cascade transitions take place in already multiply ionized configurations, and thus relative changes of the potential felt by outer-shell electrons are small. This speculation was supported by direct calculation of the final ion charge spectra produced by the decays of vacancies in the subshells of the gold atom performed with accounting for the SO processes [13].…”

“…If initial-state and final-state multiplets overlap, then in the calculation of mean transition energy and partial transition width only energetically allowed transitions between the multiplet components should be counted. In this study this routine is accomplished using global characteristics of energy spectra [38][39][40] as described in [13,16].…”

“…Theoretical description of the cascade decay of vacancies in deep electron subshells of heavy atoms is a complicated problem since the decay trees for those cascades can have enormous number of branches. To give an example, the tree for the decay of the 2s vacancy in the gold atom had 4.3•10 8 branches [13]. In theoretical description of the decay cascades, the most popular is the Monte Carlo method.…”

“…An alternative approach is based on a straightforward construction and analysis of the decay tree (CADT). This approach was realized numerically in [14,15], and its use allowed simulating rather complex cascades as, for example, the decays of K and L-shell vacancies in the gold atom [5,13,16].…”

Final ion yields and mean final ion charges upon the cascade decay of single vacancies in the K, L, M, and N shells of atomic silver are calculated using the method of construction and analysis of the decay trees with accounting for the shake-offs caused by the change of atomic core potential due to cascade transitions. The shake-off effect on the final ion yields is found to be comparatively small, the largest increase of the mean final ion charge being 0.20e in the case of initial 2s vacancy. Total semi-relativistic Pauli–Fock energies of cascade-produced ionic configurations were used to calculate cascade transition energies, which made it possible to accurately account for the closing of some non-radiative transitions in multivacancy cascade configurations. For the transitions with overlapping multiplets of initial and final ionic configurations, only energetically allowed transitions between the multiplet components were counted when calculating mean transition energies and transitions branching ratios. Comparison of calculated charge spectra with those reported earlier by other authors demonstrated crucial importance of accurate calculation of transition energies and accounting for multiplet splitting in simulation of cascades in heavy atoms.
