We calculated relativistic energies and Landé factors for 5d6s2, 5d26s, 5d^3, 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.
