Correlation and relativistic effects for the 4d  nl multipole transitions in Pdlike ions
Abstract
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 Pdlike ions with the nuclear charges ranging from Z = 47 to 100. Relativistic manybody perturbation theory (RMBPT), including the Breit interaction, is used to evaluate energies and transition rates for multipole transitions in holeparticle systems. This method is based on the relativistic manybody perturbation theory, agrees with MCDF calculations in lowestorder, includes all secondorder correlation corrections, and includes corrections from negative energy states. The calculations start from a [Zn]4p^64d^10 DiracFock potential. Firstorder perturbation theory is used to obtain intermediatecoupling coefficients, and secondorder RMBPT is used to determine the matrix elements. The contributions from negativeenergy states are included into the secondorder 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 = 47100.
