Relativistic multireference many-body perturbation calculations on multi-valence-electron systems: Benchmarks on Zn-like ions

High-accuracy calculations of term energies and wavelengths of resonance lines in Zn-like ions have been performed as benchmarks in the quest for accurate theoretical treatments of relativity, electron correlation, and quantum electrodynamic effects in multivalence-electron systems. Computed wavelengths of the 4s21S0-4s4p 1P1o transitions are compared with the recent high-resolution wavelength measurements using electron-beam ion traps [E. Traebert, P. Beiersdorfer, and H. Chen, Phys. Rev. A 70, 032506 (2004)], a sensitive means of testing electronic structure theory that has revealed the inadequacies in treating multiple valence electrons in the extant relativistic many-body calculations
