Phonons, rotons, and localized Bose-Einstein condensation in liquid He 4 confined in nanoporous FSM-16

We present neutron scattering measurements of the phonon-roton and layer modes of liquid helium confinedin 28 Å diameter nanopores of FSM-16. The goal is to determine the energy, lifetime, and intensity of themodes as a function of temperature. It is particularly to determine the highest temperature...
