Multiconfiguration Dirac–Fock calculation of Kα transition energies in beryllium like titanium

Abstract

We report calculations of energy levels and radiative rates for Kα transitions among the lowest 40 fine-structure levels in Be-like Ti XIX. The wavelengths, oscillator strengths, radiative rates and lifetimes for all possible Kα transitions have been calculated using the multiconfiguration Dirac–Fock method. The accuracy of the results is determined through extensive comparisons with existing laboratory measurements and theoretical results. These results can be used to analyze the previous experimental results and guide the design of the future experiments.
