be chosen to be 1.4*delc. The second method is, of course, approximate, but for small changes in a parameter such as c can work pretty well, and can be easier to implement than the first. --Scott Calvin Sarah Lawrence College On May 29, 2014, at 12:33 PM, Carl Brozek bro...@mit.edu wrote

[Ifeffit] Fitting EXAFS simulation to experimental

2014-05-28 Thread Carl Brozek
Dear listhost, I'm using Artemis as a front end for ATOMS and FEFF and I would like to build a simulated EXAFS spectrum based on experimental data I have. I know how to generate a simulation based on a .cif or .xyz file, but is it possible to vary parameters in these input geometries to best

[Ifeffit] modeling significant defects and molecules

2013-10-31 Thread Carl Brozek
dear listhost, I would like to use Artemis/Atoms to simulate EXAFS of a crystalline material with significant defects that include additional atoms to the unit cell. Can I simulate this material without making a new cif file? Ideally, I would be able to input a DFT-optimized model cluster as xyz
