Quantum Mechanics Illustrated Intuitively By Neutron Scattering

Quantum mechanics is one of the central pillars of modern physics. This mathematically complex theory which allows the properties and laws of matter to be described is, however, rather to understand intuitively. Generations of young scientists have approached this difficult concept with the help of double-slit experiments that clearly demonstrate wave – particle duality. Two new videos from the Jülich Centre for Neutron Science (JCNS) offer a practical alternative to this.

The videos clarify fundamental aspects of quantum mechanics using neutron scattering experiments from research undertaken at the Jülich institute. The videos are around 5 and 4 minutes in length respectively, and are appropriate for use in an introductory lecture course in quantum mechanics or for self-study purposes.

Neutrons are the building blocks of atomic nuclei and have no electric charge. They reveal, among other things, where atoms are located, how they move and which magnetic properties they possess. Due to their unique properties, scientists from many disciplines use this method, in physics through to chemistry, biology, and geology, right up to material and engineering sciences.
