Abstract:
The high-precision calculations of the structure and transition parameters for highly ionized and highly excited atoms are important in astrophysics, hot fusion experiment, distinguish of the beam-foil spectum and plasma diagnostics, particularly for the research on XUV lasers. Fine-structure levels, radiative lifetime and various transition parameters for all of the electric dipole(E1), magnetic dipole(M1), eletric quadrupole(E2) and magnetic quadrupole(M2) transitions among the 1772 fine-structure levels belong to the (1s~(2)2s~(2)2p~(6)3s~(2)3p~(6)) 3d~(10), 3d~(9)4l, 3d~(9)5l, 3d~(9)6l, 3d~(8)4s~(2), 3d~(8)4l4l' et al., and configurations of the Ni-like ions Mo XV have been calculated using the fully relativistic Multi-configuration Dirac-Fock method with the inclusion of the Breit interaction and QED corrections. The results are compared with those available in the literature, and the accuracy of the present data is assessed. Energy levels are expected to be accurate to within 0.38%. We have found some long-lived levels, which are called anomalous stability state.
