Dear XAFS Community,
I'm looking for values of absorption coefficient (or mass absorption coefficient) of ZnO in the XANES region of the Zn edge, but all the publications give XANES plots in "arbitrary units", so I have no way of knowing the absorption coefficient for ZnO.
Does anybody know a data repository where absorption coefficients are collected?
Thanks, Damon
You have ways of knowing such things. The document for my Hephaestus program lists citations for the various data resources available in my Xray::Absorption perl module: http://bruceravel.github.io/demeter/aug/hephaestus.html#credits The original data for the various resources comes with Demeter and can be browsed at: https://github.com/bruceravel/demeter/tree/master/lib/Xray/data This is is from Matt Newville and Darren Dale and it very useful: https://github.com/XraySpectroscopy/XrayDB LBL's Center for X-ray Optics is a classic resource: http://henke.lbl.gov/optical_constants/ B -- Bruce Ravel ------------------------------------ bravel@bnl.gov National Institute of Standards and Technology Synchrotron Science Group at NSLS --- Beamlines U7A, X24A, X23A2 Building 535A Upton NY, 11973 Homepage: http://xafs.org/BruceRavel Software: https://github.com/bruceravel
