[Ifeffit] UO2 thin films on STO

2010-11-16 Thread mohamed sobhy
Dear All I would like to grow UO2 thin films on STO (SrTiO3) substrate but I found that Sr K-edge 16105 and U L3-edge is 17166. Do you think there will be any interference? Best, Mohamed ___ Ifeffit mailing list

Dear I would like to fit the signal from (U0.8Ce0.2)O2, so I tried to put Ce in the same position of U but all atoms generated files give no Ce in the scattering paths and some fitting give negative amplitude values. Could you help me with the Atoms input file? Mohamed

Dear all thanks for your help and explanation about the background I fitted my data after removing the background and in the attached file I got this fitting, although all the values are good but I think the coordination number should be less than 8 (for the first shell) due to irradiation. So

Dear all I am trying to use artemis to do fitting to CeO2. But really I cant get the right way to do that. During the fitting, I am using amp as set and change in N degeneracy of the path. attached is the best fit i got but it still not good and the chi-square is 41.109065479 so can you

Dear all I am trying to fit some data of coordination number 8, but I always find the fitting of the first shell give the coordination number only about 0.5. I do not know what is wrong. Do I need to fit first and second and third shells altogether, and if that is right how Can I do that??
