Residual electronic correlation and QED effects in fine-structure splitting of ground configuration for the boron isoelectronic sequence

Forbidden M1 and E2 transition rates as well as the fine-structure splitting between 1s22s22p2P3/2and 2P1/2have been calculated using the multiconfiguration Dirac–Hartree–Fock (MCDHF) and relativistic configuration interaction (RCI) methods for the boron isoelectronic sequence with Z = 5∼92. The res...
