electron diffraction by a micron particle

Hi all,
I have a question: if there is an eletron beam (low energy, say 2ev)
hits a micro-size particle (say 20 um silica particle), will electrons
diffract around the particle and form patterns on a screen back of the
particle?
I know similarly a light may form rings (poisson spot) on the screen.
Will the same theory work for electron? Or what are required conditions
to form patterns, for example, wavelength, particle size, electron beam
radius?
Any good references/books should I look through?
Thank you very much.
Yilei
