with words alone.

Just to follow up a little on Matthew's answer:
The Darwin width is the angular width over which a particular
reflection will diffract. A rocking curve measurement usually leaves
one crystal at a fixed angle and rotates the second crystal. For a
perfectly collimated beam, the resulting intensi

example) look different?
