Abstract

We calculated relativistic energies and Lande factors for 5d6s, 5d6s, 5d, 5d6s7s, 4f6s6p, 5d6s6p, 5d6p, 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.
