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

Abstract

AbstractWe have calculated relativistic energies and Landé factors for 5d6s 2, 5d 26s, 6s6p 2, 6s 27s, 5d 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.
