Large scale calculations for the energy levels, transition rates, oscillator strengths, lifetimes, hyperfine interaction constants, Landé gJ factors, and isotope shift factors have been performed for 1s 2 and 1snl (n = 2 − 8 and l ≤ n − 1) levels of He-like Sc XX ion. The GRASP2018 package based on multiconfigurational Dirac–Fock method is used to obtain these results. The leading quantum electrodynamic corrections, Breit interaction and nuclear recoil effects are also included in the…
