Allowed and forbidden transitions in highly ionized neon-like atoms (Ni XIX-U LXXXIII)

Energy levels are calculated for highly ionized atoms of the neon sequence (Ni XIX to U LXXXIII). The multiconfigurational Dirac-Fock (MCDF) method, combined with semi-empirical corrections to the ab initio values of the energy levels, has been used for the calculations. Oscillator strengths are tabulated for 2 p -3 s , 2 p -3 d , 3 s -3 p and 3 p -3 d electric dipole (E1) transitions and for some Δ n = 1 forbidden (E2, M1 and M2) lines originating from the ground state.
