# Particle Double slit

How was the Particle Double Slit Experiment really done? To be precise, what kind of double slits were used and how can such slits be small enough, especially for electrons and buckys balls?

• Not exactly a double slit but electron diffraction by crystals is related. In that case the rows of atoms in the crystal act as multiple slits. – M. Enns Jan 29 at 15:54
• One can use a wire at high voltage. This acts as a biprism. I think that is how they did C$_{60}$ in Aarhus. – Pieter Jan 29 at 15:55
