Abstract

In this paper, we present a study of the photoionization of Rydberg series of Ytterbium (Yb I) and Indium (In I) atoms, focusing on the 6sns 1S0 and 6snd 1,3D2 states for Yb and 5s2np 2P1/2 and 5s2nf 2F5/2 states for In. The main objective is to calculate the resonances energies of these states using the Screening Constant per Unit Nuclear Charge (SCUNC) formalism. A semi-empirical method widely used in atomic physics to predict the energies of excited states without requiring the calculation of photoionization cross-sections.
