• If de Broglie’s concept is correct, electrons should exhibit the  wave properties of diffraction and interference.

• A good “slit” could be the spacings between atoms in a crystal.

• In 1927, C. Davisson and L. Germer guided a beam of electrons at  a nickel crystal and obtained an electron diffraction pattern.

• This observation proves that electrons  behave as waves under some conditions.
