Hello Matt Sir, Thanks a lot for your valuable sugestions. I had fitted the Cu foil spectra as you suggested. I had taken same SO2 value for all the paths and after fitting the first shell , making its parameter fix when fitting second shell I changed the fit R range 2.9- 3.7 in order to make the contribution of first shell negligible. I got a nice fit. The values of different parameters I got are as follows : E 0=2.90 eV , SO2= 0.72 1st shell R = 2.54, delR= -0.011, SS2=0.0083 2nd shell R= 3.69, delR= 0.080, SS2=0.0088 The experimental data is taken at room temperature. Are these parameters within the experimental error limit. Please tell me with regards Abhijeet Gaur

Those values seem like the right range for room temperature Cu to me. Channeling those who taught me: be sure to include error bars in those fitted values! --Matt
