Pole figures are tough, they require a good understanding of the mechanisims of XRD, and the method of creating them. You'll also find some fundamental knowledge of the structures of your bronzes. I think that the bronzes used in ancient times are primarily cold worked to shape, right? The cold working will introduce lattice deformations that will affect the 2(theta) angle and the atom spacings that cause diffraction.

The book on diffraction I used in school was: "Elements of X-Ray Diffraction" 2nd Ed. by B.D. Cullity, Addison Wesley, c.1978, ISBN: 0-201-01174-3

Ch. 9 has what seems to be a good discussion on pole figures and how to analyze them. IIRC this was a tricky subject when I was in structural charecterization.

Are you currently associated w/ a University? If so go the the metallurgy department and ask for the XRD expert. This may be a prof, or it may be the technical staff that runs the machine. At my university both were great for helping figure stuff out.

(on a side note: Are you studying industrial arechology? where at?)

I love materials science!

Thank you all for your advices! We perform neutron diffraction analysis on roman and etruscan bronzes (coins, mirrors, blades) dated V-III B.C. century.It's a quite new field and so it's difficult to find books or articles related to it.
I am a Physicist but metallurgy and metallography is a topic for engineers..
Thanks again

Professor Sean Agnew at the University of Virginia has published work using neutron diffraction and custom software.  Look at his publications:

Numbers 1 & 5 should be very helpful.
