Energy Levels, Lifetimes, And Transition Probabilities For Rb(Xxiii)

Energy levels, radiative rates, lifetimes, hyperfine structures and Lande g(J)-factors for electric-dipole (El), electric-quadrupole (E2), magnetic-dipole (M1), and magnetic-quadrupole (M2) transitions among the lowest 41 levels belonging to the n = 3 states (1s(2)2s(2)2p(6))3s(2)3p(3), 3s(3)p(4), and 3s(2)3p(2)3d in Rb(XXIII) are calculated through the multiconfiguration Dirac-Hartree-Fock method. High-accuracy calculations have been performed as benchmarks in the request for accurate treatments of relativity, electron correlation, and quantum electrodynamic effects in multi-valence-electron systems. The calculated energy levels are in excellent agreement with the experimental results and the theoretical ones, wherever available. The calculated values including core-valence correction are found to be in good agreement with other theoretical and experimental values. The present results are reported as benchmarks for future calculations and measurements.
