Spectroscopic investigations of the structure of highly ionised atoms have undergone
significant developments in recent years. The experimental progress is largely due to the …

Wavelengths, transition rates, and line strengths are calculated for the 76 possible multipole
(E1, M1, E2, M2, E3, and M3) transitions between the excited 3s23p63d94l, 3s23p53d104l …

The atomic structure of the low-energy configurations of the zinc-like ions (Rb VIII to W XLV)
has been analyzed in detail. A Multiconfiguration Dirac-Fock (MCDF) technique has been …

The calculation of global or mean characteristics-variance, skewness and excess-of energy
level spectrum, using their explicit expressions, is described. The usefulness of these …

Relativistic configuration-interaction calculations of the 4s4p excitation energies and 4s 2–
4s4p E1 transitions for Zn-like ions from Z= 30 to 92 are shown. B-spline basis functions are …

We report on large scale ab initio calculation for the 4s 2 1 S 0–4s4p 1, 3 P 0, 1, 2 transitions
in the zinc-like sequence, using the multiconfiguration Dirac–Fock (MCDF) method. Our …

Energy levels, with designations and uncertainties, have been compiled for the spectra of
strontium (Z= 38) ions from singly ionized to hydrogen-like. Wavelengths with classifications …

The energies of the 44 even-parity and 40 odd-parity (4 l 4 l′) states of ions of the zinc
isoelectronic sequence are determined through second order in relativistic many-body …

New measurements of the Cu-like and Zn-like resonance lines classified as 4s? S2_1/2-4p?
P21/2, 3/2∘ and 4s^ 2? S1_0-4s4p? P1, 31∘ transitions, respectively, have been made in …

Empirical predictions are reported for the lifetimes of the 4s^ 2–4s4p resonance and
intercombination transitions in the Zn isoelectronic sequence. The approach uses a direct …
