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