(a) Calculated absorption spectra of Ga in langasite crystal (total) and partial absorption spectra corresponding to Ga1, Ga2 and Ga3 positions per atom near the Ga K-edge. (b) Calculated XNCD spectra ( = ) of langasite crystal (total) and tensor components spectra corresponding to Ga1 (), Ga2 () and Ga3 () positions near the Ga K-edge. |
