Spectral investigation of doubly ionized rubidium (Rb III) from relativistic Hartree-Fock calculations

Abstract

Radiative decay parameters (oscillator strengths, transition probabilities) for spectral lines in doubly ionized rubidium (Rb III) are reported for the first time. They have been obtained using a pseudo-relativistic Hartree-Fock (HFR) model including a large amount of intravalence correlation as well as core-polarization effects. The spectroscopic data listed in the present paper cover a wide range of wavelengths from extreme ultraviolet to near infrared.
