Sultan The dynamics of superfluid He 4 at and above the Landau quasiparticle regime is investigated by high-precision inelastic neutron scattering measurements of the dynamic structure factor. A highly structured response is observed above the familiar phonon-maxon-roton spectrum, characterized by sharp thr… [Phys. Rev. B 94, 024504] Published Mon Jul 11, 2016
