Aims.In this paper we report calculations for energy levels, radiative rates and excitation rates for transitions in Ni xi.
Methods.The grasp (General-purpose Relativistic Atomic Structure Package) and fac (Flexible Atomic Code) have been adopted for calculating energy levels and radiative rates, and the Dirac Atomic R-matrix Code (darc) has been used to determine the excitation rates.
Results.Oscillator strengths, radiative rates and line strengths are reported for all E1, E2, M1 and M2 transitions among the lowest 250 levels of Ni xi. Additionally, lifetimes are also reported for all levels. However, results for excitation rates are presented only for transitions among the lowest 17 levels.
Key words: atomic data, atomic processes
