Abstract

High-resolution inelastic neutron scattering measurements of the dynamic structure factor S(q, omega) of superfluid He-4 at the roton minimum are presented. The temperature dependence of the roton energy and line width at 24bar between 0.8 and 1.1 K are reported. (C) 2000 Elsevier Science B.V. Allrights reserved.
