Natale,
I suggest that you contact Peter Burns in the Dept of Geology at Notre Dame
(ph: 219-631-5380; or try [EMAIL PROTECTED], I'm not sure of the e-mail
address)
Peter works with XRD at very small angles, some for spacings in the 40Å
range. The signal is caught on a charge coupled device and digitized so
that he can do structural analysis.
