Hi James,
Well, I think there's q (or s) which depending on where you're coming
from can be 4*pi* sin(theta)/lambda, or 2*sin(theta)/lambda, or ..... *
sin(theta)/lambda) or .... or .... * sin(theta)/lambda.
Small-angle X-ray scattering (and other fields) uses those as symbols
for the momentum transfer vector. I think for SAX I mainly saw s being
used, and for imaging mainly q, but I could be mistaken.
I myself am always confused by those measures as the prefactor varies
from author to author, as does the unit for the wavelength (Angstrom or
nm).....
Bye,
Thomas
