    "abstract": "A relativistic many-body method is developed to calculate energy and\ntransition rates for multipole transitions in many-electron ions. This method\nis based on relativistic many-body perturbation theory (RMBPT), agrees with\nMCDF calculations in lowest-order, includes all second-order correlation\ncorrections and includes corrections from negative energy states. Reduced\nmatrix elements, oscillator strengths, and transition rates are calculated for\nelectric-multipole (dipole (E1), quadrupole (E2), and octupole (E3)) and\nmagnetic-multipole (dipole (M1), quadrupole (M2), and octupole (M3))\ntransitions between 3l5l\u0027 excited and ground states in Ni-like ions with\nnuclear charges ranging from Z = 30 to 100. The calculations start from a\n1s22s22p63s23p63d10} Dirac-Fock potential. First-order perturbation theory is\nused to obtain intermediate-coupling coefficients, and second-order RMBPT is\nused to determine the matrix elements. A detailed discussion of the various\ncontributions to the dipole matrix elements and energy levels is given for\nnickellike tungsten (Z = 74). The contributions from negative-energy states are\nincluded in the second-order E1, M1, E2 M2, E3, and M3 matrix elements. The\nresulting transition energies and transition rates are compared with\nexperimental values and with results from other recent calculations. These\natomic data are important in modeling of M-shell radiation spectra of heavy\nions generated in electron beam ion trap experiments and in M-shell diagnostics\nof plasmas.",
