Dear all,

It is possible to use in Artemis several paths from 2 different FEFF input files in one fit for the unknow sample? Also could I manipulate directly in the feff input file, I mean change elements and so on. 

Thanks,
Damdin

Dear IFEFFIT users,


I  have some problems/doubts with quite basic questions concerning xanes processing. In particular the normalization range. Can anyone  please  look at my project  and tell me if my data processing is correct ?
 The xanes are at the Fe K-edge, of a F(II)-complex,  taken at different temperatures.

In fact my question  concerns  the choice of the starting value for the normalization range.  I obtain  reasonable lines with a starting point  from  more that 100 eV after E0. Is it correct to start so far from the edge??    should one start just after the broad feature (onset of exafs ?  ) ?
if I start the post-edge normalization before ..I obtain different results when I compare the different xanes..


thanks for your help,
best regards,
bahia
