Energies and Landé factors for some excited levels in Lu I (Z = 71)

We have calculated relativistic energies and Landé factors for 5d6s2, 5d26s, 6s6p2, 6s27s, 5d3, 5d6s7s, 6s26p, 5d6s6p, 5d26p and 6s27p excited levels outside the core [Xe]4f14 in neutral lutetium (Lu I, Z = 71). These calculations are based on the multiconfiguration Hartree-Fock (MCHF) method, within the framework of the Breit-Pauli relativistic corrections. Moreover, the results obtained have been compared with other works.

Transition Parameters for Doubly Ionized Lanthanum

The transition parameters such as the wavelengths, weighted oscillator strengths, and transition probabilities (or rates) for the nd , nd , np , and ng electric dipole (E1) transitions of doubly ionized lanthanum (La III, ) have been calculated using the relativistic Hartree-Fock (HFR) method. In this method, configuration interaction and relativistic effects have been included in the computations combined with a least squares fitting of the Hamiltonian eigenvalues to the observed energy levels. We have compared the results obtained from this work with the previously available calculations and experiments in literature. We have also reported new transitions with the weighted transition probabilities greater than or equal to 105.

Energies, Landé g-factors, and lifetimes for some excited levels of doubly ionized lanthanum

Using the relativistic Hartree-Fock (HFR) method developed by Cowan, we calculated the energy levels, Landé g-factors, and lifetimes for nd (n = 5–25), ns (n = 6–24), ng (n = 5–25), nf (n = 4–22), and np (n = 6–25) excited levels of doubly ionized lanthanum (La III, Z = 57). We compared the results with previously reported calculations and experiments.

Transition Energies of Ytterbium (Z=70)

Abstract Transition energies of neutral ytterbium (Yb I, Z = 70, belonging to the lanthanide series), including ionization potential, excitation energies, and electron affinity are calculated by the multiconfiguration Hartree-Fock (MCHF) method within the framework of the Breit-Pauli Hamiltonian and the relativistic Hartree-Fock (HFR) method. Ionization potential and excitation energies of Yb II and Yb III are also reported. The obtained results have been compared with other works.

These calculations have been carried out by using the multiconfiguration Hartree-Fock method within the framework of the Breit-Pauli Hamiltonian (MCHF
