Theoretical Ca K-edge (upper panel) and S K-edge (lower panel) XANES of CaS obtained in the full-potential (FP) mode either in the real space (for a cluster of 123 atoms) or in the reciprocal space, together with XANES obtained for a spherical potential (ASA) in the reciprocal space. The calculations were performed using the SPRKKR code; the core hole was not taken into account. The experimental XANES of Xu et al. (2013) is shown for comparison. |
