Energy levels, lifetimes and transition data for Cu-like Nd31+ to Br-like Nd25+ ions

We have performed calculations for Cu-like to Br-like neodymium (Nd) ions using the multiconfiguration Dirac–Hartree–Fock (MCDHF) and relativistic configuration interaction (RCI) approaches. An extensive set of fine structure energy levels, lifetimes, wavelengths, and radiative transitions for electric and magnetic multipole transitions is provided. We systematically include the electronic correlation effects between valence electrons and two subshells of core electrons. In the RCI procedure, both the Breit interaction and the leading quantum electrodynamic effects are taken into account. The reliability and accuracy are confirmed by comparing our results to accessible experimental and theoretical data.
