Relativistic many-body calculations of lifetimes, rates, and line strengths of multipole transitions between 3l(-1)4l' states in Ni-like ions

Transition rates and line strengths are calculated for electric-multipole (E2 and E3) and magnetic-multipole (M1, M2, and M3) transitions between 3s(2)3p(6)3d(10), 3s(2)3p(6)3d(9)4l, 3s(2)3p(5)3d(10)4l, and 3s3p(6)3d(10)4l states (with 4l= 4s, 4p, 4d, and 4f) in Ni- like ions with the nuclear charges ranging from Z= 34 to 100. Relativistic many-body perturbation theory (RMBPT), including the Breit interaction, is used to evaluate retarded multipole matrix elements. Transition energies used in the calculation of line strengths and transition rates are from second-order RMBPT. Lifetimes of the 3s(2)3p(6)3d(9)4s levels are given for Z= 34 - 100. Taking into account that calculations were performed in a very broad range of Z, most of the data are presented in graphs as Z dependences. The full set of data is given only for Ni- like W ion. In addition, we also give complete results for the 3d4s D-3(2)- (3)d4s D-3(1) magnetic- dipole transition, as the transition may be observed in future experiments, which measure both transition energies and radiative rates. These atomic data are important in the modeling of radiation spectra from Ni- like multiply charged ions generated in electron beam ion trap experiments as well as for laboratory plasma diagnostics including fusion research.
