Wavefunctions for ground state 4f³ 6s² configuration of praseodymium to calculate energy of fine levels and other spectroscopic quantities

Abstract

Wave functions for terms with the same orbital angular momentum L and spin angular momentum S, but different parents can be written as a linear combination of the pure parentage wave functions. These wavefunctions are important because various spectroscopic quantities e.g. energy and transition probability can be calculated with the help of these wavefunctions. In this study we present 46 wavefunctions of seventeen terms (
