Relativistic many-body Møller–Plesset perturbation theory calculations of the energy levels and transition rates in Na-like to P-like Xe ions

Abstract

Relativistic multireference many-body perturbation theory calculations have been performed for Xe 43+ to Xe 39+ ions, resulting in energy levels, electric dipole transition rates, and level lifetimes. The second-order many-body perturbation theory calculation of energy levels included mass shifts, the frequency-dependent Breit correction, and Lamb shifts. The calculated transition energies and E1 transition rates are used to present synthetic spectra in the extreme ultraviolet range for some of the Xe ions.
