(a) A non-resonant X-ray emission spectrum of the Cu Kβ emission line, as well as the valence-to-core part of the same emission line of a copper-exchange zeolite. (b) An Si L2,3-edge excitation spectrum measured at high momentum transfer q and (c) an O K-edge spectrum at low momentum transfer of the same sample. The XES spectra were measured simultaneously to the two XRS spectra. |
