Aims.In this paper we report calculations for energy levels and radiative rates for transitions in Ni XIX.
Methods.The General purpose Relativistic Atomic Structure Package (grasp) has been adopted for the calculation of energy levels and radiative rates.
Results.Energies for the lowest 89 levels from the (1s2) 2s22p6, 2s22p53
, 2s2p63, 2s22p54 and 2s2p64 configurations of Ni XIX, are reported. Additionally, radiative rates, oscillator strengths, and line strengths are reported for all electric dipole (E1), magnetic dipole (M1), electric
quadrupole (E2), and magnetic quadrupole (M2) transitions among these levels. Comparisons are made with the available results in the literature, and the accuracy of the present
data is assessed. Finally, lifetimes for all excited levels are listed, and comparisons made with earlier available theoretical results.
Key words: atomic data / atomic processes
