Energy levels, lifetimes, and transition probabilities for Sr XXXII

Abstract

The fully relativistic multiconfiguration Dirac–Hartree–Fock (MCDHF) approach was used to calculate the excitation energies and lifetimes for the lowest 272 levels that belonging to the $$2{s}^{2}2{p}^{3}$$ 2 s 2 2 p 3 , $$2s2{p}^{4}$$ 2 s 2 p 4 , $$2{p}^{5}$$ 2 p 5 , $$2{s}^{2}2{p}^{2}3l$$ 2 s 2 2 p 2 3 l , $$2s2{p}^{3}3l$$ 2 s 2 p 3 3 l , and $$2{p}^{4}3l$$ 2 p 4 3 l ($$l=s, p, d$$ l = s , p , d ) configurations for N-like strontium, Sr XXXII, as well as the wavelengths, weighted oscillator strengths, transition probabilities, and line strengths for the electric dipole (E1), electric quadrupole (E2), magnetic dipole (M1), and magnetic quadrupole (M2) transitions among these levels. The Breit-interaction (BI), and quantum electrodynamics (QED) corrections have been incorporated into the computations. In order to assess the uncertainties of the current calculations, comparisons with available data, and the results from the largest MCDHF layers have all performed.
