摘要：

We have developed a new experimental method for measuring extremely small changes in kinetic energy in a flux of atoms. Analogously to the well-known technique of neutron spin echo, we have succeeded in manipulating the nuclear spins in an atomic beam of He-3. The result, He-3 spin echo, is a universal,high intensity, high resolution tool for a wide range of areas in physics and molecular sciences. We describe the experimental setup and show first spin echo curves. In addition, we demonstrate the power of the method by resolving a change in energy of the He-3 atoms of ca. 33 neV.
