Helium-3 surface spin echo is a technique used primarily in the field of condensed matter physics to probe the properties of liquid helium-3 (³He) near surfaces, usually in the context of studies involving superfluidity and quantum phenomena. Helium-3 is notable because it is a fermionic isotope of helium, and it can exhibit superfluid behavior at very low temperatures.
