Greetings,

I'm looking for x-ray absorbtion coefficients for SiO2 (LTO) and SiNx (PECVD)
and Aluminum. I'm specifically interested in values corresponding to
wavelengths of 2-10 Angstroms, but values at other wavelengths would be useful
as well.

Thanks for any info,
Ken

Ken,
You are in LUCK, because MOXTEK has developed for commercial and
scientific use a program called MOXGRAF which calculates the
x-ray optical constants for any compound you want to type in
for the energy range 10 eV to 30 keV, in eV or angstoms,
and not only that, but will calculate transmission, reflection
beta, delta, f1, f2, and just about anything else and PLOT
it in full color for your entertainment and edification.  And
best of all it costs not $1000, not $100, but for the low
low price of FREE!

The bad news is that no one here has been motivated to put it on
our website, so you have to request it.  And the policy for
requesting it is to FAX the request, not to e-mail it.  The
FAX number is 801-221-1121.

best regards
mark
