Transition energies of neutral ytterbium (Yb I, Z = 70, belonging to the lanthanide series), including ionization potential, excitation energies, and electron affinity are calculated by the multiconfiguration Hartree–Fock (MCHF) method within the framework of the Breit–Pauli Hamiltonian and the relativistic Hartree–Fock (HFR) method. Ionization potential and excitation energies of Yb II and Yb III are also reported. The obtained results have been compared with other works.
Key words: MCHF Method; HFR Method; Energy Levels; Relativistic Corrections.
