Systematic studies of highly excited Rydberg states in ions with two valance electrons
(2006) In Journal of Physics B: Atomic, Molecular and Optical Physics 39(12). p.2815-2826- Abstract
- A method, based on the multiconfiguration Hartree-Fock approach, for ab initio calculations of Rydberg states has been developed. The method has been tested for a number of highly excited Rydberg states, with quantum numbers l = 4 - 8 and n <= 9, in Mg-like and Be-like ions. The results are compared with Hartree-Fock calculations to investigate the influence of correlation and, to a lesser extent, relativistic effects. The theoretical spectra for Cl VI and the lifetimes of the 2s6g-levels in O V are in excellent agreement with experimental results. More limited calculations have also been done for some Rydberg series in S V and Ar VII to illustrate the changing influence of perturbers along the isoelectronic sequence. The difficulties... (More)
