[en] The energies and lifetimes of doubly excited sextet states of boron-like O IV, F V, and Ne VI are calculated
with the multiconfiguration Hartree-Fock approach, including QED and higher-order corrections, and also with
the multiconfiguration Dirac-Fock GRASP code. The wavelengths and transition rates of electric-dipole transitions
from the inner-shell excited terms 1s2s2p23s 6P–1s2p33s 6So are investigated by beam-foil spectroscopy
in the XUV spectral region. The predicted transition wavelengths agree with the experiment. The higherorder
corrections, fine structures, and spectrum with high wavelength resolution are found to be critically
important in these comparisons. Nine new lines have been identified. The ground sextet states of boronlike
atoms are metastable and well above several ionization levels. These are possible candidates for XUV and soft
x-ray lasers.
