The Merli–Missiroli–Pozzi Two-Slit Electron-Interference Experiment

Abstract: In 2002 readers of Physics World voted Young’s double-slit experiment with single electrons as “the most beautiful experiment in physics” of all time. Pier Giorgio Merli, Gian Franco Missiroli, and Giulio Pozzi carried out this experiment in a collaboration between the Italian Research Council and the University of Bologna almost three decades earlier. I examine their experiment, place it in historical context, and discuss its philosophical implications.

“…The first real single-electron interference experiments that were conducted were electron-biprism experiments (for a review see Refs. 47,48) in which single electrons either pass to the left or to the right of a conducting wire (there are no real slits in this type of experiments). [49][50][51] In these experiments the interference pattern is built up from many independent detection events.…”

“…In the two-slit experiment, placing a quantum system on one side of the two slits produces a series of single, bright spots at specific, unpredictable locations on the screen on the other side of the slits. In this sense the system exhibits particle properties, at a specific time and place on the screen [303,304]. If both slits are open then, when sufficiently many spots have appeared on the screen, an interference pattern emerges.…”

“…In the quantum mechanics framework, the same kind of double-slit experiment can be performed with electrons, leading to the same kind of interference patterns. It shows that matter exhibits wave-duality behavior, exactly like light (Merli, Missiroli, Pozzi, 1976) (Rosa, 2012). In order to describe it, the d'Alembertian"s equation of propagation =0, is then replaced by the non relativist Schrödinger equation (ih/2)/t +(h 2 /8 2 m)=0.…”
