Theoretical Level Structure and Decay Dynamics of Nickel-like Ions: Search for Laser Lines in the Soft X-ray Domain
Abstract
Multiconfiguration Dirac-Fock wave functions have been applied to study the level structure and transition probabilities of high-Z nickel-like ions in the range 74 ≤ Z ≤& 84. Several level crossings are found which strongly influence the decay dynamics of the excited ions and explain why some of these lines cannot (so easily) be observed for all elements along the isoelectronic sequence. For two selected ions, the role of configuration interactions and relaxation is explored by large-scale expansions.
