We have calculated relativistic energies, Landé factors, and lifetimes for some excited levels outside the core [Xe] in neutral ytterbium (Yb I, Z=70) using two configuration interaction methods (multiconfiguration Hartree-Fock method within the framework of Breit-Pauli relativistic corrections developed by Fischer, and Cowan's relativistic Hartree-Fock method). Results obtained have been compared with other calculations and experiments.

We calculated relativistic energies and Landéfactors for 5d6s², 5d²6s, 5d³, 5d6s7s, 4f6s6p, 5d6s6p, 5d²6p, and 4f5d6s levels in neutral lanthanum (Z=57). We also obtained electric dipole transition energies and lifetimes for some excited levels. The calculations are based upon the multiconfiguration Hartree-Fock method within the framework Breit-Pauli relativistic corrections. Moreover, the results obtained were compared with other calculations and experiments.

We calculated hyperfine structure constants of the 5d6s^{2}, 5d^{2}6s, 5d^{3}, 5d^{2}7s, 5d6s7s, 5d6p^{2}, 4f^{2}5d, 4f6s6p, 5d6s6p, 5d^{2}6p, 4f5d6s and 4f5d^{2} levels for ^{139}La I (Z=57). The calculations are based upon the multiconfiguration Hartree-Fock method within the framework of the Breit-Pauli relativistic corrections. Moreover, the results obtained were compared with other available calculations and experiments.

Transition Parameters for Doubly Ionized Lutetium

Karaçoban B., Özdemír L.

EN
Using the relativistic Hartree-Fock method developed by Cowan, we calculated the electric dipole (E1) transition parameters such as the wavelengths, the weighted oscillator strengths, and the transition probabilities (or rates) for doubly ionized lutetium (Lu III, Z=71). We compared the results with available calculations and experiments in literature. A discussion of these calculations for Lu III in this study has also been made in view of the relativistic Hartree-Fock method.
