Blurness of rings in electron diffraction

Hi guys,

I just did an experiment about electron diffraction the other day, and I had a really difficult time measuring the radii of the rings because they were quite blurred at the edges. Anyone knows why they are so blur, especially for the first (innermost) ring?

Welcome to PF;
The probably blur for similar reasons that the fringes in Youngs interference are blurry.

Does the theory predict definite clear boundaries for the rings?

It depends on the apparatus. Can you give us more details about the apparatus?
