English abstract
Energies, transition rates, line strengths and lifetimes have been computed for all levels of the 4p6 and 4p54d configurations of W38+ by using the multi-configuration Dirac–Hartree– Fock (MCDHF) method as well as relativistic many-body perturbation theory. We investigate systematically correlation, relativistic and quantum electro-dynamical (QED) effects of different properties, including excitation energies and transition rates. We demonstrate that it is important to include the core-valence correlation of rather deep subshells (including 3d and 3p) to reach close to spectroscopic accuracy for the transition energies. We also show that high-multipole transitions (E3, M2) are important for the lifetime of some metastable levels of 4p54d (3F3;1 D2;3 D2). The present results are in good agreement with experiments and of considerably higher accuracy than those achieved in previous theoretical works.
