cross- section that is very close to the wavelength of the photoelectron. Consequently, the photoelectron is not scattered back to the absorbing atom efficiently at this energy. Perhaps someone in the list can explain this more clearly (or correctly). Sincerely, Wayne Lukens On Nov 5, 2006

Re: [Ifeffit] Artemis fitting using FEFF paths plus experimentalreferences

Hi Matthew, It sounds like you have a problem caused by the finite size of the nanoparticles, which results in lower than expected amplitude of the shells in comparison to the amplitude of the shells generated from the xtal structures of maghemite and magnetite. If this is the case and you have

Hi Andreas, The problem was that for the atoms in position 6c, the sum of x and y must be exactly 1. I have attached a corrected atoms.inp file that seems to work. Sincerely, Wayne Lukens Voegelin Andreas wrote: Dear all, Using Atoms (latest version of Artemis), I tried to calculate a Feff

Hi Julian, This looks like an example of the Ramsauer-Townsend effect. Maybe someone who has a stronger physics background can explain it, but here is a reference. Phys Rev B, 1995, 52, 6332-6348. Sincerely, Wayne On Tue, Oct 4, 2011 at 9:08 AM, Kaiser, Julian
