State-specific configuration interaction in the continuum calculations, with electron correlation included, shows that shape resonances in polyelectronic atoms can be computed systematically to a high degree of accuracy. Specifically, the B- 1s22s22p2 1D state is computed to be a shape resonance with Ε=95 meV and Γ=54 meV, confirming the tentative identification given recently by Lee et al. [Phys Rev. A 53, R633 (1996)] for the lowest resonance structure observed in scattering experiments.
