Dynamical phenomena at the atomic scale influence and control a wide range of processes occurring on surfaces of solids. A fundamental understanding of the forces guiding surface motion is thus of utmost importance for the advancement of many fields of science and technology. Helium-3 spin-echo spectroscopy is uniquely suited to study adsorbate diffusion and vibrations experimentally, probing motion in a regime of length- and timescales that is not currently accessible by any other technique.
