Hi to all, I would like to ask you which is the status of the discussion on the self-absorption corrections to fluorescence EXAFS. I'm working on Mo/Si multilayers, studied by standing-wave-assisted EXAFS. My data are collected at grazing incidence (phi + theta = 90 deg) with a Ge (13 elements) detector. I have done data analysis without self-absorption corrections and I have found good results, except for the amplitude (S_0^2) that is very low (~0.50). I think this low value is due to self-absorption, so I would like to demonstrate it. My dilemma is: Troger's approach or Booth's one? I personally think that Booth's (simple) approach, could be used in this particular case (Ge detector, phi+theta=90deg), but my tutor told me that I can't assume a neglectable solid angle for a Ge detector so I have to use the Troeger's (quite difficult) approach.
From the mailing-list archive, I have read your discussion about this topic but I haven't found something like a "conclusion". Is there anyone who use Booth's approach with good results? Have you already done "tests" of this method? Is it possible to improve it?
Finally, what about the software status? Matt, have you done something on
Booth's Fortran code?
Thanks,
Mauro
