Abstract:
Radiative and Auger decay data have been calculated for modeling the K
lines of the aluminium isonuclear sequence, from Al0 to Al11+. 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.
