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 http://www.xafs.org/Common_Mistakes Shelly From: [EMAIL PROTECTED] on behalf of Scott Calvin Sent: Wed 7/16/200

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

Matthew - as you know, it's trivial to just let b=1/a and the write the distribution as (x-x)^s Exp[- (x-x0)/b] so that the gaussian limit is obtained as b->0. So infinite parameters are not a problem. Your suggestion and other observations are quite right. In fact, if convoluting distribu

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: Plotting the mue (4th column in xmu.dat) of a FEFF8.4 S
