[Ifeffit] Amplitude ratios greater than 100%

Dear All, With the attached CIF file, i have generated chi and other files. In turn, for some paths, i have found amplitude ratios are greater than 100% (even it is reaching few thousands % for some paths - chi file also attached with this email). I know, it is meaningless. I would like to know, w

[Ifeffit] Bump/oscillating pattern at high energies of EXAFS

Dear All, I have monitored the growth process of YbVO4 nanoparticles using EXAFS. Here, nanoparticles were synthesized in water medium. Both initial and final products (EXAFS) of the synthesis were measured using the continuous flow approach whereas the intermediate products were recorded, in the

[Ifeffit] In-situ bulk data analysis

Dear All, I am looking for an EXAFS software to handle bulk data and perform both linear combination and regular EXAFS fit. Regards, Raj ___ Ifeffit mailing list Ifeffit@millenia.cars.aps.anl.gov http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit

Hi Scott, I would like to add an extra point to the previous message. Yes, i am getting a large uncertainty for the second so2 (2.04 +/- 1.36). Regards, Raj On 3 January 2017 at 21:32, Raj kumar wrote: > Hi Scott, > > Thank you very much for your prompt response. EXAFS measurement

Hi Guanghui, Final particle size of these nanoparticles are about 30-40 nm. Regards, Raj On 23 December 2016 at 19:00, wrote: > Send Ifeffit mailing list submissions to > ifeffit@millenia.cars.aps.anl.gov > > To subscribe or unsubscribe via the World Wide Web, visit > http://mi

[Ifeffit] Web Atoms 1.8 vs Demeter 0.9.26: feff output are not same

Dear All, Recently, i found out that feff.inp generated by web atoms and Demeter 0.9.26 are not the same. My main worry is in the position of atoms. For evidence, i am attaching YbVO4 (*feff.inp*) files generated by both web atoms and Demeter. With this kind of zircon type structure, one would exc

[Ifeffit] Peak at short distance in FT - YbVO4 nanoparticles

Dear All, Recently, i have performed EXAFS for YbVO4 bulk (prepared through sintering process) and nanoparticles (at room temperature). Nanoparticles were synthesized by co-precipitation technique and their EXAFS was measured by passing the prepared solution using peristaltic pump. After all subtr

[Ifeffit] (D)Artemis shutting down automatically

Dear All, Recently, i have faced automatic shutting down of artemis during the import of chi file. For more clarification, please see the first log file. Also, i observed emptying of .fpj files. This happens during the saving of old .apj to .fpj or/and during the frequent saving of .fpj files aft
