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 succeeding relativistic configuration interaction calculations. The relativistic isotope shift (RIS4) program is used to determine the mass and field shifts factors. A detailed comparison of the present results with the corresponding values from the NIST database and other theoretical work, wherever available, has been done, and an excellent agreement is achieved. A large section of the results is reported for the first time in the present work.
