Scott, Bruce, Matt, Kelly, Grant and all,

Thank you for your advice. I am really appreciate that.I think I have to give 
more detail about my analysis results and make it more clear.

1. I took the fluorescence spectrum.
2. I checked the pre-edge and post-edge lines and they looked reasonable. 
3. I took the three first shell paths(Vanadium-Oxide) to fit the data. and I 
set amp, e0, delr, ss for the variables.
4. The degeneracy of the paths are the same as calculated by FEFF6
5. the following results

    amp = 0.316    +/-   0.108
    e0  = 5.053    +/-   4.321
    delr= 0.003    +/-   0.025
    ss  = -0.003   +/-   0.004
6. the correlations between amp and ss =0.88
                            e0  and delr = 0.86

I don't know if any other information can help to solve this problem. Thank 
you for your help.

By the way, Grant, the papaer you mentioned, is that from " J. J. Rehr, C. H. 
Booth, F. Bridges, and S.I. Zabinsky, Physical review B, 49,12347, 1994"? Or 
other else? Can you give me more detail about that?

Good day
Yu-Chuan
