POSSIBLE DETERMINATION OF THE HELICITY OF ELEMENTARY EXCITATIONS IN LIQUID He II

Journal Article · · Phys. Rev. Letters
The energy-momentum curve of the excitations in liquid helium were directly measured by the inelastic scattering of cold neutrons. It is found that associated with a definite momentum transfer of the neutron there is a definite energy traasfer. It is customary to call these excitations "phonons" and "rotons." The angular momentum of these excitations is investigated by studying the angular distribution of the scattered neutrons. (A.C.)
