Abstract

The aim of this study was to obtain a description of the neutral lutetium spectrum. We calculated the radiative parameters (wavelengths, weighted oscillator strengths and transition probabilities) for electric dipole (E1) transitions for some excited levels in neutral lutetium (Lu I, Z = 71). Two configuration interaction methods were used: the multiconfiguration Hartree–Fock method developed by Fischer within the Breit-Pauli relativistic framework (MCHF + BP), and Cowan’s relativistic Hartree–Fock (HFR) method. Results obtained have been compared with each other and with other works. A discussion of these calculations for Lu I in this study has also been in view of the MCHF + BP and HFR methods.
