A Young's-type double-slit experiment using electron beams carrying orbital angular momentum (OAM) is demonstrated in a transmission electron microscope. Each of the slits is replaced by a grating mask with a fork dislocation, which generates electron beams with OAM as diffracted beams. Interference fringes produced by two diffracted electron beams with OAM appear at the observation screen. The interference fringe patterns exhibit dislocation features depending on the topological charges of the two electron beams. The experimental results clearly show the wave nature of the electron beams with OAM and gives potential applications in electron physics and quantum mechanics.
