Any references to this quantity in more recent papers seem to point back to the 1981 Lee/Citrin/Eisenberger/Kincaid Rev. Mod. Phys. Review - http://dx.doi.org/10.1103/RevModPhys.53.769 (see p. 794 in particular).

Hello,

I was recently asked about the accuracy of this formulation for obtaining EXAFS resolution and I did not have a good answer. Can someone point to a reference or explain here?

Thank you for your time,

Best,
