Yah know,,,I'm wrong The last one is a triple scattering path with just two
scattering atoms. the leg part is right...

Hi Eckhard,
The first slide also has problems. The first path is a single scattering path.
All the others are double scattering paths. The word "single", "double" and
"triple" are used to describe the number of atoms that scatter. The number of
legs is used to tell the difference between t
I'd like to add my 2cents worth about the mean square displacement term. I
wrote it up on the EXAFS wiki, since I like to say it over and over. see

Hi Rich,
"Mean-square radial disorder" (MSRD) is one good alternative.
I'll also point out another bit of ambiguity with "Debye-Waller
factor" aside from the confusion with the XRD term. Some EXAFS
practitioners use Debye-Waller factor to indicate all disorder-type
modifications to the EXAF

Hi Eckhard,
the printout you have was taken from lectures given by Paolo Fornasini, from
Trento (Italy). You can probably find them on the web.

Hi Eckhard,
I Googled one of the phrases, and found this as a source:

lezione_assorbimento.ppt
Perhaps you can check on that site to find out more.

Dear all!
Recently I read the two inspiring XAFS13-contributions of Shelly and Bruce
dealing with the energy-shift (p.132) and the use of SCF-calculations (p. 137).
In this respect I have a question regarding the Enot parameter in Artemis:
