We are organizing this conference to provide an opportunity for researchers in North America to gather and present their research in years when there is no International XAFS Conference. One of the major goals is to have a high degree of participation from students and postdoctoral scientists in both the oral and poster sessions. On behalf of the organizing committee, I would like to invite you to give a talk at one of our sessions. Since we are leaving the logistical organization of this conference to the ICDD Conference Staff, we can offer the same reduced registration fee that is provided to the Denver X-ray Conference invited speakers. The plans for the conference include a symposium in honor of Ed Stern on Tuesday, August 3, a poster session and a series of oral sessions running concurrently with the Denver X-ray Conference sessions. We hope that you can accept this invitation, and look forward to seeing you in Denver. Sincerely yours, Carlo Segre, for The Organizing committee. -- Carlo U.

Dear Bruce, I am trying to fit EXAFS data for Arrojadite (a naturally occuring phosphate mineral) measured on Fe-edge. When i load crystallogrphic file in to FEFF, i get Degeneracy (N) for all path as 1 or 2. I know from the crystal structure of Arrojadite that it is not true. Kindly help me in solving this problem. Best regards, Jatin

Re: [Ifeffit] Emission spectra of Cobalt (Timna-Josua Kuehn)
by Timna-Josua Kuehn 14 Apr '10

Hi Joshua, thanks for this explanation of the XES command. I was not aware of it. However, I can not find the data file of the XES simulation yet, although no error is reportet! There is some file called "xsect.dat", where something about "em" is written, but there are no XES spectra in it. Does one have to process this file's data or even some more files?

Emission spectra of Cobalt
by Timna-Josua Kuehn 12 Apr '10

12 Apr '10

Dear all, I am trying to simulate Cobalt Kbeta emission spectra. Actually I just exchanged the XANES card with XES, as is explained and set emin = 7700 eV and emax = 7800 eV with estep = 100 to calculate the whole Co Kbeta line at 7649.43 eV. But I do not find a file that contains the emission data. I thankful for each helpful advice.

No background subtraction in some cases?
by Alexander Riskin 02 Apr '10

02 Apr '10

Dear all, Recently we've measured samples at the DUBBLE Beamline at ESRF for iron and molybdenum (K-edge). After measuring, the DUBBLE software generates a .dat file which must then be translated to other files (depending on the fact whether transmission or fluorescence is measured) using some script in linux. When we try to import some of these transformed files (for transmission measured) into Athena however, the program fails to subtract a background from mu(E), therefore no k and R-space plots are available (see project files MoPEL002 and MoPEL004, the original dat.sample files are included in the zip files). Other files however, work fine (both transmission and fluorescence measured ones). After analyzing the structure of the .dat files, it was discovered which columns are the Io an It data and the correct ln(Io/It) could be manually generated. This manual procedure yields data sets identical to the ones in the dat.sample files, we named them dat.good files. When importing these files into Athena, the background subtraction works fine. It is the exact same data however... Although the problem can be bypassed by processing the data manually, the fact that Athena processes some files correctly and others not seems very strange to us since they all come from the same beamline. We thought it would be interesting to let you all know. Thanks for your time and for making such wonderful software, Alexander Riskin -- Alexander Riskin Universiteit Hasselt IMO - Inorganic and Physical Chemistry Agoralaan – Building D BE-3590 Diepenbeek / Belgium tel. +32.(0)11.26.83.94 fax. +32.(0)11.26.83.23 email: alexander.riskin(a)uhasselt.be
