摘要/Abstract

摘要： Systematic calculations and assessments are performed for the magnetic dipole (M1) transition energies and rates between the $^{2}\!F^{\rm o}_{5/2},_{7/2} $ levels in the ground configuration {4d}$^{10}${4f} along the Ag-like isoelectronic sequence with ${62 } \le Z \le { 94}$ based on the second-order many-body perturbation theory implemented in the Flexible Atomic Code. The electron correlations, Breit interaction and quantum electrodynamics effects are taken into account in the present calculations. The accuracy and reliability of our results are evaluated through comprehensive comparisons with available measurements and other theoretical results. For transition energies, our results are in good agreement with the recent experimental data obtained from the electron beam ion traps within 0.18%. The maximum discrepancy between our results and those obtained with the large-scale multiconfiguration Dirac-Hartee-Fock calculations by Grumer et al. [Phys. Rev. A 89 062501 (2014)] is less than 0.13 % along the isoelectronic sequence. Furthermore, the corresponding M1 transition rates are also reported. The present results can be used as the benchmark and useful for spectra simulation and diagnostics of astrophysical and fusion plasmas.
