We have calculated relativistic energies and Landé factors for 5d6s
3, 5d6s7s, 6s
26p, 5d6s6p, 5d
26p and 6s
27p excited levels outside the core [Xe]4f
14 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.
