Spectral data and grotrian diagrams for highly ionized nickel, Ni IX-Ni XXVIII

Wavelengths, energy levels, level classifications, oscillator strengths, and radiative transition probabilities for the nickel ions Ni IX to Ni XXVIII are critically reviewed and tabulated. Grotrian diagrams are also presented to provide graphical overviews. The literature has been surveyed to mid-1986.
