Title: Relativistic multireference many-body perturbation theory calculations on Au64+ - Au69+ ions

Abstract

Many-body perturbation theory (MBPT) calculations are an adequate tool for the description of the structure of highly charged multi-electron ions and for the analysis of their spectra. They demonstrate this by way of a re-investigation of n=3, {Delta}n=0 transitions in the EUV spectra of Na-, Mg-, Al-like, and Si-like ions of Au that have been obtained previously by heavy-ion accelerator based beam-foil spectroscopy. They discuss the evidence and propose several revisions on the basis of the multi-reference many-body perturbation theory calculations of Ne- through P-like ions of Au.

  • Many-Body Perturbation Theory (MBPT) has been employed to calculate with high wavelength accuracy the extreme ultraviolet (EUV) spectra of F-like to P-like Xe ions. They discuss the reliability of the new calculations using the example of EUV beam-foil spectra of Xe, in which n = 3, {Delta}n = 0 transitions of Na-, Mg-, Al-like, and Si-like ions have been found to dominate. A further comparison is made with spectra from an electron beam ion trap, that is, from a device with a very different (low density) excitation balance.
  • Energies of the ground and a number of even- and odd-parity excited states of multi-valence-electron ions have been computed by a computational method in the framework of relativistic multireference many-body perturbation theory. Relativistic multireference perturbation calculations are reported for the ground and over 80 low-lying odd- and even-parity excited states of siliconlike argon (Ar{sup 4+}) and aluminumlike iron (Fe{sup 13+}) to demonstrate the unprecedented accuracy of the method. The theory deviates from experiment by less than 0.2% for all but a few excited levels in siliconlike argon. For the more highly ionized aluminumlike iron, the deviations are reduced to withinmore » 0.06%. Theoretical magnetic dipole and electric quadrupole transition rates of the lowest-lying {sup 2}P{sub 3/2}{sup o} state of aluminumlike Fe and Mn are evaluated, and lifetimes are compared with a recent ion trap experiment.« less
  • 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 4s{sup 2} {sup 1}S{sub 0}-4s4p {sup 1}P{sub 1}{sup o} 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.
  • A recently developed relatistic multireference many-body perturbation theory based on multireference configuration-interaction wavefunctions as zeroth order wavefunctions is outlined. The perturbation theory employs a general class of configuration-interaction wve functions as reference functions, and thus is applciable to multiple open valence shell systems with near degeneracy of a manifold of strongly interacting configurations. Multireference many-body perturbation calculations are reported for the ground and excited states of chlorine-like Fe X in which the near degeneracy of a manifold of strongly interacting configurations mandates a multireference treatment. Term energies of a total of 83 excited levels arising from the 3s{sup 2}3p{sup 5},more » 3s3p{sup 6}, 3s{sup 2}3p{sup 4}3d, 3s3p{sup 5}3d, and 3s{sup 2}3p{sup 3}3d{sup 2} configurations of the ion are evaluated to high accuracy. Transition rates associated with E1/M1/E2/M2/E3 radiative decays and lifetimes of a number of excited levels are calculated and compared with laboratory measurements to critically evaluate recent experiments.« less
  • Relativistic multireference many-body perturbation theory calculations have been performed on Xe{sup 43+}-Xe{sup 39+} ions, resulting in energy levels, electric dipole transition probabilities, and level lifetimes. The second-order many-body perturbation theory calculation of energy levels included mass shifts, frequency-dependent Breit correction and Lamb shifts. The calculated transition energies and E1 transition rates are used to present synthetic spectra in the extreme ultraviolet range for some of the Xe ions.
