B K-edge XANES of calciborite (upper panel) and ludwigite (lower panel) calculated for two different ways of accounting for the core hole: either it is included using the relaxed and screened model (solid lines) or it is included using the (Z + 1)* scheme (broken lines). Non-self-consistent potentials were employed. Experimental spectra are shown via dotted lines. The origin of the energy scale is arbitrary. |
