This work presents an accurate determination of various parameters of Ar13+. The calculated wave functions, energy levels, and properties are in agreement with existing theoretical and experimental results.
An accurate determination of various parameters of Ar13+ is presented in this work. The wave functions and energy levels of the low-lying states within the configurations of 2s(2)2p and 2s2p(2) are calculated using the fully relativistic multiconfiguration Dirac-Hartree-Fock method, while the wave functions of higher excited states with the configurations 2s(2)nl (n >= 3, l = s, p, d) are obtained using the relativistic configuration interaction plus core polarization method. Then, the absorption oscillator strengths, transition probabilities, polarizabilities, and g factors are determined. The contributions of electron correlation effects, Breit interaction, and quantum electrodynamics effects are also investigated. The present results agree well with the available theoretical and experimental results. The g factors of the 2s(2)2p P-2(1/2,3/2) states agree with the experimental measurements on a level of 10(-)(6).
