Level energies, transition wavelengths, radiative transition probabilities, and radiative and Auger widths have been determined using Cowan's Hartree-Fock with relativistic corrections (HFR) method. Results are compared with data sets computed with the AUTOSTRUCTURE and GRASP atomic structure codes and with available experimental and theoretical values, mainly in highly ionized ions and in the solid state. Description: Computed level energies, wavelengths, radiative transition probabilities, absorption oscillator strengths, radiative and Auger widths, and K-shell fluorescence yields in Al0-Al11+ are given in these two tables. In Table 14 levels are identified by the electron number (N), the level index, the spin multiplicity, the total orbital angular momentum quantum number, the total angular momentum quantum number and the electronic configuration. For each level, the computed HFR energy and its radiative width are listed. For K-vacancy levels, the Auger width and the K-shell fluorescence yield are also given. In Table 15 transitions are identified with the electron number, the upper and lower level indices tabulating its computed wavelength, radiative transition probability, weighted oscillator strength, and cancellation factor. The empirically shifted wavelengths are given for 4≤N≤8. File Summary:
