Chi in arthemis
by Eugenio Otal 18 Aug '09

Hi Scott, I forget the amp, I left the N =1, that is the mistake, sorry I have de S02 from other oxide to transfer it. I found that error bars in Ifeffit are scaled by Chi2 reduced, so should I transform the error or inform them directly as reported? Regards, euG

Chi in arthemis
by Eugenio Otal 18 Aug '09

Hi all, I see that the reports of the fits a perform in arthemis have Chi really big. The fit is really good and the Chi should be closer to 1 than to 100. The problem, is what should I report as the Chi. Uncertain in delr or ss have the same problem, are big like the results. I found the topic in the list but not a good answer to what should I report. Thanks, euG

Is it legitimate to merge transmission data with fluorescence data?
by jrkizews＠ncsu.edu 11 Aug '09

11 Aug '09

Dear XAFS community members, I have a question concerning data merge. We normally collect XAFS data in both transmission mode and fluorescence mode. We normally have to merge a few scans to enhance signal-to-noise ratio. For one particular sample, I want to know if it is legitimate to merge its transmission scans with its fluorescence scans to improve data quality? I appreciate any input. Regards.

Re: [Ifeffit] Installation of FEFF8 on IFEFFIT

Han, I am CCing my answer to the Ifeffit mailing list, as this is an appropriate question for the list. Artemis is quite happy using Feff8 for EXAFS analysis, although the advantage of Feff8 for EXAFS analysis over Feff6 is rather marginal. You will need to configure Artemis to use Feff8 correctly. In the Edit menu, select Edit preferences. Change the Atoms->feff_version parameter to 8. Then change the Feff->feff_executable parameter to the fully qualified location of the Feff8 executable. That is, you must type in something like "C:\Software\Feff8\feff8.exe". To the best of my knowledge, that will work correctly.

Re: [Ifeffit] Kapton in glove box (Todd Monson)
by Monson, Todd 06 Aug '09

06 Aug '09

Thanks for all your comments regarding kapton tape and measuring air and moisture sensitive compounds. Many of my samples are indeed air sensitive and not just moisture sensitive (iron nanoparticles). If my particles are dispersed in solvent will the kapton be resistant to that solvent (at least during the time that the solvent is evaporating from the tape in the glove box)? Darek mentioned kapton dots - could you tell me where I can purchase these? Thanks again for everyone's help, I thought this mailing list was primarily for software related questions but I am finding it is useful to get help on any XAFS related questions.
