A trivial question about terms.
What should be called "scattering angle" in Bragg's low: theta or 2*theta ?
In my view, the "scattering" angle is 2*theta (the angle between the
incident and the scattering directions), while theta is the "reflection"
angle (the angle between the incident or diffracted ray and the reflecting
crystal planes).
However, I hear sometimes calling theta the scattering angle. Is this just
a misuse of the term ?
