Hi, all I wonder if anyone can suggest me on how to set up restrain of a parameter in GDS, for example, to restrain ss in a certain range or no negative. Thank you so much. Dien Li

XANES from FEFF9
by manju rao 13 Jul '18

13 Jul '18

Hi. I am trying XANES simulation in FEFF9. My system of calculation is SrZnO2 and I am simulating Sr K edge. I noticed that on changing SO2 card from 0.0 to 1.0, there is change in position as well as profile of absorption edge. Also, by selecting or deselecting EXCHANGE card, some changes are also there. So, which approach is to be followed to obtain trust-able spectra? Please help. Manju Research Scholar Department of Physics Punjabi University, Patiala- 147 002 Punjab, India.

Importing 100 element Ge data into Larch
by Macon Abernathy 13 Jul '18

13 Jul '18

Hey all, Has anyone had success loading data from larger pixel arrays into Larch? I have data collected on a 100 element Ge detector that results in Athena crashing upon import (running on Mac OS 10.13.4, Demeter v9.25). I figure this is a good task for Larch, but am having a difficult time figuring out how to import all 100 channels for each data set simultaneously. Thanks in advance for any tips, Cheers, Macon J.

Re: [Ifeffit] window 10
by manju rao 13 Jul '18

Hi Dien I guess this is the problem with new version too. ARTEMIS could run once for any calculation with no time limit, but if I open new data file, it got crashed. So I do one fitting at a time and then restart it for new fitting. Regards Manju Sent from my iPhone

Hi, Bruce and Matt We just transitioned to Window 10 yesterday. I just found that as I ran Artemis for EXAFS data fitting, it constantly crashed (stopped running) my computer, I am using Demeter 9:24 I believe, is it possible I need a new version, where is the link for latest version? Thanks. Dien Li Savannah River National Laboratory

Fe Standards
by Naomi Intrator 10 Jul '18

10 Jul '18

Hi all, I'm doing a project on Fe and was wondering if anyone has spectra of Fe(II) and/or Fe(III) standards they wouldn't mind sharing. I'm specifically looking for XANES of Fe2+ and Fe3+ ions in water. Thanks in advance, Naomi ---

copper fluoride
by Bruce Ravel 10 Jul '18

Hi all, I wonder if anyone has a spectrum of copper fluoride, CuF2, that they are willing to share. This would be a big help for my undergraduate student's summer research project. Thanks!

imaginary part
by John Hummel 10 Jul '18

10 Jul '18

I have run a feff calculation in artemis and pulled the information from the output file in an attempt to sum the paths in python. However I am having some difficulty in determining the imaginary part of the waves. I was wondering how the artemis program goes about calculating the imaginary values. Any insight would be greatly appreciated. Thank you, John
