Abstract

Radiative and Auger decay data have been calculated for modeling the K lines of the aluminum isonuclear sequence, from Al⁰ up to Al¹¹⁺. Level energies, transition wavelengths, radiative transition probabilities, and radiative and Auger widths were 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.
