Transition energies, oscillator strengths and lifetimes of the excited states for boron-like ions, Ne+5, Na+6 and Mg+7, 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. Transition energies are compared with experiment and other results.
