Wavelengths, transition rates, and line strengths are calculated for the 85 possible multipole (E1, M1, E2, M2, E3, M3) transitions between the excited 4p^64d^94f, 4p^64d^95l, 4p^54d^104f, and 4p^53d^105l states and the ground 4p^64d^10 state in Pd-like ions with the nuclear charges ranging from Z = 47 to 100. Relativistic many-body perturbation theory (RMBPT), including the Breit interaction, is used to evaluate energies and transition rates for multipole transitions in hole-particle systems. This method is based on the relativistic many-body perturbation theory, agrees with MCDF calculations in lowest-order, includes all second-order correlation corrections, and includes corrections from negative energy states. The calculations start from a [Zn]4p^64d^10 Dirac-Fock potential. First-order perturbation theory is used to obtain intermediate-coupling coefficients, and second-order RMBPT is used to determine the matrix elements. The contributions from negative-energy states are included into the second-order E1, M1, E2, M2, E3, and M3 matrix elements. The resulting transition energies and transition rates are compared with experimental values and with results from other recent calculations. The Z dependence of the energy splitting for all triplet terms of the 4p^64d^94f and 4p^64d^95l configurations are shown for Z = 47--100.
