I agree, this is a sign of a poor background subtraction. I find that this
can be mitigated by cutting back on your spl;ine range for background
subtraction. Change it by 0.5 at a time or less and keep plotting in
k-space. You might have to lose a bit of range but that just means that
the data
It's possible that your data really has a kink in it. Zoom in on that
last bit in E space before any background subtraction and see if there's
something odd-looking. If there's really an artifactual kink, then
there's not much you can do.

Dear Danting,
did you look on the background that is subtracted? I guess it is your
background that is doing something weird here. To look at the background
tick "Background" in the plot. In the region you mention it should be a
smooth line without visible oscillations.
Cheers,

Hi Mr/Ms,
I am a new learner of XAS and meet a problem like before and hope you can give
me some hints.

I have a data set after merged and alignment. But at 11-13 A-1, the amplitude
of k is much higher than normal but
