Dear Prof.;

  Here have some questions about Zn doped LiNbO3 single crsystal

EXAFS fitting problem, we did the similar EXAFS absorption spectra

as you can see the attach reference paper Fig 7, that shows

double picks on Near Edge region, and our questions are,

 

(1) Base on your great knowledge, how comes about these

    two picks, and is it normal?

(2) On Artemis program R-figure display, we can find a great pick

    appeared in 0~1 angstrom range (k range=1~12), but we find

    this pick disappeared under (k range=2~12) parameter choosing

    ,so is it relation to question (1)?

(3) If we want to cut near edge contribution, how should we deal with

    these double picks? choose the rear EXAFS spectrum (aviod these

    two picks)? Or using Athena background removal it?

 

Thanks for your time and helping.
