Wow! A diffkk question. Such a blast from the past!
Have you examined the examples Matt provides at
Diffkk isn't exactly a DAFS analysis program, but it's a tool that may
be useful for analyzing your dafs. Diffkk takes XAFS data as input,
converts it to f" and does a Kramers-Kronig transform to make an f'
function with fine structure wiggles. There is a lot more to dafs
analysis than just that.
I'm not sure if anyone who contributes regularly to the list has done a
dafs experiment recently. I certainly haven't. I'm not sure if any
packaged software is available. Many of us wrote our own in a one-off
manner. That's what I did.
Perhaps someone else can comment....
