Atomic data for opacity calculations: XXIV. The boron-like sequence

Energy levels, oscillator strengths and photo-ionization cross sections are calculated for all levels with n10 in boron-like ions of the elements C, N, O, Ne, Na, Mg, Al, Si, S and Fe. The R-matrix method is used. Particular attention is paid to the determination of accurate wavefunctions for the Be-like `target' states in configurations 1s22s2,1s22s2p and 1s22p2.
