The UCN, with wavelengths » interatomic spacing are affected by the space average of these potentials which is about 10. eV for many materials. On total reflection the UCN wavefunction penetrates into the reflecting surface and can be absorbed or upscattered by the thermally vibrating nucleii located there.

Existence of the polarized component suggests that the repulsive interaction is also important to investigate the Raman scattering process of simple liquids as well as conventional dipole-induced-dipole interaction.

Introduction: Suffering’s Dead? energies below the bulk roton value are also visible in the neutron scattering of a thick film and even if the film is extended to bulk liquid . Thus these excitations have to be localized near the solid liquid interface. These modes show only little or no dispersion, they exhibit localized
