Dear All,
My target is the L3-edge of Pt foil and Pt-contained high-entropy alloy.
In the Pt foil L-edge FT-EXAFS (k range: 3-20 A-1), there is a strange peak
lower than the first near neighboring peak.
This low-r peak makes confused because I did not found in other metal foil
spectra.
Also this peak cannot be reduced by increasing the Rbkg value.
When I decrease the k range, this strange peak disappears with phase shift.
In the Pt-contained high-entropy alloy, this strange peak becomes more
pronounced than the 1st NN.
Can anyone can give me help interpret this strange peak?
Best regards,
Fan
