For quantum liquids, .He and .He, the ratio of the polarized component to the total intensity has been observed to increase in the large energy shift region. Pressure dependence has been measured both for super and normal fluid .He. For liquid .He, the integrated intensity r

A collection of atoms appears as a group of hard sphere repulsive potentials to a neutron. The UCN, with wavelengths » interatomic spacing are affected by the space average of these potentials which is about 10.

Introduction: Suffering’s Dead?e substrate used in this work was graphite. Two layers adjacent to the substrate can be solidified due to the van der Waals attraction with the graphite. The densities of the layers are very different, displaying through the high compressibility of the helium the dependence of the van der Waals forc

Later studies also demonstrated the inadequacy of the Born Approximation as a result of the resonant structure, and hence extensive theoretical progress was achie

The Social Bases of Self-Respect,In the neutron experiments, however, this asymptotic branch by PITAEVSKII has not been observed up to the end point Q. The peak position is found to be at rather higher energy than twice the roton energy at large momentum transfer. This report shows that, at finite temperatures, due to the finite li
