Atomic structure calculations of some lanthanide atoms

In this study, energy levels, Landé g-factors, transition energies, wavelengths, oscillator strengths, transition probabilities, lifetimes and hyperfine structure constants for lanthanide atoms, La (Z = 57), Ce (Z = 58), Yb (Z = 70) and Lu (Z = 71), and some their ions have been calculated using multiconfiguration Hartree-Fock (MCHF) and relativistic Hartree-Fock (HFR) approximations which are configuration interaction methods.In the first chapter previous works on La, Ce, Yb and Lu atoms and some of their ions have been given. Second chapter deals with Hartree-Fock approximation, the multiconfiguration Hartree-Fock and relativistic Hartree-Fock methods. Wave functions and some relativistic corrections have been calculated using the MCHF atomic structure package and Cowan?s program package. In the third chapter results obtained have been compared with other experimental and theoretical works.
