Abstract
The spectra originating from the electric dipole transitions of nd (n = 3 − 5) core excited states to the 5f valence states of Am2+ to Am8+ ions have been calculated using the Dirac-Hartee-Fock method, which are compared with the results from the Flexible Atomic Code for the explanation of accuracy. It is found that both the M4,5(3d→5f) and N4,5(4d→5f) spectra of these ions consist of two peaks that are well separated in energy respectively by 202.11 eV and 49.10 eV due to strong spin-orbit interaction of the 3d−1 and 4d−1 hole state, while the O4,5(5d→5f) spectra show a broad quasi-continuum profile.
