Abstract

Calculations of complete energy level schemes for 4fⁿ and 4fⁿ⁻¹5d¹ electronic configurations of free trivalent rare-earth ions have been performed. Semi-empirical Hamiltonian was used for the calculation of 4fⁿ configuration while a fully relativistic first-principles many-electron method was used for the calculation including 4fⁿ⁻¹5d¹ configuration. As a result, Dieke’s diagram is extended to about 200000 cm⁻¹ in the case of 4fⁿ electronic configurations and about 370000 cm⁻¹ in the case of 4fⁿ⁻¹5d¹ electronic configurations. Calculated energy levels are plotted as a function of the atomic number.
