Accurate multiconfiguration calculations of energy levels, transition rates, and lifetimes for Kr XXIII

Extensive Multiconfiguration Dirac-Hartree-Fock calculations are performed for the lowest 97 levels belonging to the 3s(2)3p(2), 3s(3)p(3), 3s(2)3p3d, 3s3p(2)3d, 3s(2)3d(2), and 3p(4) configurations in silicon-like Kr XXIII. Complete and consistent data sets of energy levels, transition rates and lifetimes for electric-dipole (E1), electric-quadrupole (E2), magnetic-dipole (M1), and magnetic-quadrupole (M2) transitions among all these levels are given. High-accuracy calculations have been performed with accurate treatment of relativity, electron correlation, and quantum electrodynamic effects, as well as inter-electron correlation. The calculated energy levels are in excellent agreement with available theoretical and experimental data. The present results are reported as benchmarks for future calculations and measurements.
