Abstract: | Measurements of inelastic neutron scattering from liquid 4He were performed at very large momentum transfer (about 150 Å−1) using an eV spectrometer with a pulsed spallation neutron source. A difference in the scattered neutron spectrum measured at 1.2 and 2.5 K was observed for the first time within this momentum-transfer range. |
