英文摘要	Energies, transition rates, line strengths and lifetimes have been computed for all levels of the 4p(6) and 4p(5)4d 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 4p(5)4d (F-3(3), D-1(2), D-3(2)). The present results are in good agreement with experiments and of considerably higher accuracy than those achieved in previous theoretical works.; Swedish Research Council [2015-04842]; International Exchange Program Fund of doctoral students under the Fudan University Graduate School; NSAF of China [11076009]; National Natural Science Foundation of China [11374062]; Chinese Association of Atomic and Molecular Data; Chinese National Fusion Project for ITER [2015GB117000]; Shanghai Leading Academic Discipline Project [B107]; SCI(E); EI; ARTICLE; tomas.brage@fysik.lu.se; chychen@fudan.edu.cn; 13; 49
