Dear Tien, The difference is that the two spectra were measured in different modes: transmission mode (ln(I0/It)) vs fluorescent mode (If/Io). Regarding the spectrum provided by your colleague, the jump step is quite low. Also the measured intensity is much larger than that of the white line, which may have caused your Lytle detector overloaded.

I am confusing about the two plots. Could you please explain more about the difference? https://www.researchgate.net/publication/231097049_Cs_L-edge_EXAFS_atomic_absorption_background/figures?lo=1 Kind regards, N. C.

According to the attached figure, I don't understand why mu(E) increased with increasing energy before and after the L3 edge. Does it make sense for cesium? Thanks.
