Homework Help: Interference and diffraction

  1. Nov 24, 2008 #1
    A certain crystal has a planar spacing of .25nm. What energies are necessary to observe up to three interference (diffraction) maxima for a)electrons and b)neutrons?

    What have you tried? What do you know about diffraction through a crystal? What equations do you know that give the interference maxima for this type of diffraction?
