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.
