Title: Energy levels, oscillator strengths, line strengths, and transition probabilities in Si-like ions of La XLIII, Er LIV, Tm LV, and Yb LVI

Abstract

Detailed calculations using the multi-configuration Dirac–Fock (MCDF) method are carried out for the lowest 64 fine-structure levels of the 3s{sup 2}3p{sup 2}, 3s{sup 2}3p3d, 3s3p{sup 3}, 3s3p{sup 2}3d, 3s{sup 2}3d{sup 2}, and 3p{sup 4} configurations in Si-like ions of La XLIII, Er LIV, Tm LV, and Yb LVI. Energies, oscillator strengths, wavelengths, line strengths, and radiative electric dipole transition rates are given for all ions. A parallel calculation using the many-body perturbation theory (MBPT) method is also carried out to assess the present energy levels accuracy. Comparisons are performed between these two sets of energy levels, as well as with other available results, showing that they are in good agreement with each other within 0.5%. These high accuracy results can be used to the modeling and the interpretation of astrophysical objects and fusion plasmas. - Highlights: • Energy levels and E1 transition rates of Si-like ions are presented. • Breit interaction and Quantum Electrodynamics effects are discussed. • Present results should be useful in the astrophysical application and plasma modeling.

  • Fine-structure calculations of energy levels, oscillator strengths, and transition probabilities for transitions among the terms belonging to 3s{sup 2}3p{sup 2}, 3s3p{sup 3}, 3s{sup 2}3p3d, 3s{sup 2}3p4s, 3s{sup 2}3p4p, 3s{sup 2}3p4d, 3s{sup 2}3p5s and 3s{sup 2}3p5p configurations of silicon-like ions P II, S III, Cl IV, Ar V and K VI have been calculated using configuration-interaction version 3 (CIV3). We compared our data with the available experimental data and other theoretical calculations. Most of our calculations of energy levels and oscillator strengths (in length form) show good agreement with both experimental and theoretical data. Lifetimes of the excited levels are alsomore » given.« less
  • 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 used for investigating the level crossings and compositions in the n = 4 configurations. Transition probabilities have been calculated in both the Coulomb and the Babushkin gauges for all the transitions involving the 34 lowest energy levels. Level energies, wavelengths, transition probabilities, and oscillator strengths are tabulated for Ag XVIII to W XLV.
  • We have calculated fine-structure energy levels, oscillator strengths and transition probabilities for transitions among the terms belonging to the 1s{sup 2}2s{sup 2}2p{sup 6} ns ({sup 2}S), 1s{sup 2}2s{sup 2}2p{sup 6} np ({sup 2}P), 1s{sup 2}2s{sup 2}2p{sup 6} nd ({sup 2}D) (n = 3, 4, 5), and 1s{sup 2}2s{sup 2}2p{sup 6} nf ({sup 2}F) (n = 4, 5) configurations. The calculations are based upon the general configuration-interaction code CIV3 of Hibbert which uses orthonormal orbitals of radial functions expressed as superpositions of normalized Slater-type orbitals. Our calculated values are compared with experimental and other theoretical results where a satisfactory agreement ismore » found. We also report on some unpublished energy values and oscillator strengths.« less
  • Energy levels, oscillator strengths, and transition probabilities for transitions among the 14 LS states belonging to configurations of sulfur-like iron, Fe XI, have been calculated. These states are represented by configuration interaction wavefunctions and have configurations 3s{sup 2}3p{sup 4}, 3s3p{sup 5}, 3s{sup 2}3p{sup 3}3d, 3s{sup 2}3p{sup 3}4s, 3s{sup 2}3p{sup 3}4p, and 3s{sup 2}3p{sup 3}4d, which give rise to 123 fine-structure energy levels. Extensive configuration interaction calculations using the CIV3 code have been performed. To assess the importance of relativistic effects, the intermediate coupling scheme by means of the Breit–Pauli Hamiltonian terms, such as the one-body mass correction and Darwin term,more » and spin–orbit, spin–other-orbit, and spin–spin corrections, are incorporated within the code. These incorporations adjusted the energy levels, therefore the calculated values are close to the available experimental data. Comparisons between the present calculated energy levels as well as oscillator strengths and both experimental and theoretical data have been performed. Our results show good agreement with earlier works, and they might be useful in thermonuclear fusion research and astrophysical applications. -- Highlights: •Accurate atomic data of iron ions are needed for identification of solar corona. •Extensive configuration interaction wavefunctions including 123 fine-structure levels have been calculated. •The relativistic effects by means of the Breit–Pauli Hamiltonian terms are incorporated. •This incorporation adjusts the energy levels, therefore the calculated values are close to experimental values.« less
  • Extensive configuration interaction calculations for the 2s{sup 2}2p-2s2p{sup 2} transitions for several ions along the B I isoelectronic sequence (Al ix, Mn xxi, Fe xxii, Co xxiii, Ni xxiv, Cu xxv, Zn xxvi, Mo xxxviii, and Au lxxv) have been calculated using the grasp2 k package based on the multiconfiguration Dirac-Hartree-Fock (MCDHF) method. By employing active-space techniques to expand the configuration list, we also included Breit interaction and quantum electrodynamical (QED) effects to correct atomic state wave functions and the corresponding energies. Both valence correlation and core polarization effects are included, the latter being significant in achieving agreement between lengthmore » and velocity forms of the oscillator strengths of related allowed transitions. The fine-structure energy levels, term splitting, transition energies, transition rates, line strengths, and thereby the branching ratios are compared with experimental data and with values from other calculations.« less
