Debye model on artemis
by Kleber Daum Machado 11 May '10

11 May '10

I'd like to use the third cumulant option in Artemis, but considering the Debye model. Artemis has a Debye function for the second cumulant (Debye-Waller factor) but not to the third. How could this be done in Artemis? Kleber

values of f(k),δ(k) and λ(k)
by Neetu parsai 11 May '10

11 May '10

Hello, Can some one give me the values of theoretically calculated functions f(k),δ(k) and λ(k), that can be used in EXAFS equation to calculate structural parameters. If these values are given in FEFF, how can I get those. I require it to use in EXAFS equaiton using some another computer program. Thanks Mrs.Neetu Parsai Head Department of Engg.Physics Sanghvi Innovative Academy Indore. Residence: 130 Hemu colony, New G.D.C.Road, Indore-452015(M.P.) India.

Yes I am new to EXAFS, so no offense taken. Thanks for the link on how to do it. ~Corisma ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

asking for model compound data
by María Elena Montero Cabrera 10 May '10

10 May '10

Hello to all! I have looked to Matt Newville's data for model compounds, and I have not found those for gamma-Fe2O3, so called maghemite. Carlo Segre has provided me those from Litle Library, I thank very much his kindness. He has suggested me to obtain this way newer data. Would any of you provide me that, please?

Thanks for responding Mohamed. I previously had looked at the website that you mentioned (http://cars9.uchicago.edu/~newville/adb/search.html) but did not see either files (TiAl or TiAl3) on there. Do you or anyone else know of another place I can look? ~Corisma Robinson ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

Fwd: All that old figures
by Eugenio Otal 10 May '10

Hi, when I was writing my thesis I get bored to see the old figures of photoelectrons scattering in the classical books (*Konigsberger *, etc). So I decided to make them again. Hope it is useful.

energy resolution
by M Ceolin 05 May '10

05 May '10

Hi all. I would like to know if anyone knows an experimental method to determine the energy resolution in the XANES region of a XAS spectrum. I do not explored the previous entries in the list so I beg you pardon if it was already discussed. Thank you for the information.

Differences between fluorescence and transmission of the same sample
by Andrew Campos 05 May '10

05 May '10

Dr. Ravel, Thanks so much for the link and the advice! I appreciate it greatly. I will advise my lab mates as such and may have to only use the fluorescence data if that is indeed the case. I also included the file where the lower temperature is included and you might come to the same conclusion. The samples that I ran were pre-sieved, and the ones included in the .prj file aren't so that should be pursued prior to running the experiment. If they crush the particle and sieve the sample, I think that we can be more certain that this is not the case. This was very helpful! Andrew

Dr. Dixon, Thanks for your input! As you can see I'm really not completely sure what the problem is, and the fact that you're getting something similar with your in situ fuel cell experiments is encouraging. I will try and see what is the best course of action from this and from Dr. Ravel's advise as well! Thanks for all the help! Andrew
