QED effects in transition energies of low lying levels for highly ionized boron like ions

Transition energies of the lowest 1s22s22p 2P3/20 and 1s22s2p24P1/2 states for boron-like ions (Z from 31 to 60) have been calculated using multireference relativistic configuration interaction method based on the no-pair Dirac–Coulomb–Breit Hamiltonian. Analytic basis sets of Gaussian-type functions are employed to expand the upper and lower components of the Dirac four-spinors in the matrix Dirac–Fock self-consistent field and relativistic MR CI procedures. QED corrections were calculated using hydrogenic and screened self energy model.
