  • Description: <jats:title>Significance</jats:title> <jats:p> In bound matter on all length scales, from nuclei to molecules to macroscopic solid objects, most of the density of the bound particles is within the range of the interaction potential which holds the system together. Quantum halos on the contrary are a type of matter where the particle density is mostly outside the range of the interaction potential in the tunneling region of the potential. Few examples of these fascinating systems are known in nuclear and molecular physics. The conceptually simplest halo system is made of only two particles. Here we experimentally image the wavefunction of the He <jats:sub>2</jats:sub> quantum halo. It shows the predicted exponential shape of a tunneling wavefunction. </jats:p>
