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 the different kinds of double scattering. So the first (A-B-A) single scattering path has 2 legs (nlegs=2). The next one (A-C-B-A) is a double triangle scattering path with 3 legs. The next one (A-B-C-A) is equivalent to the previous one so that the CN for that path is twice the number of atoms for that path. The last one (A-C-B-C-A) is a double scattering path with 4 legs.

Can anybody tell me the author etc...? I searched everywhere on the web (on several sites of XAFS-Summer Schools...). Unfortunately i do not have the talk as pdf-file only the print out. Maybe the talk is from Matt Newville? Maybe anybody recalls on this talk/slides or recognizes them? Thanks for your help.
