Neutron reflection from a liquid helium surface

The reflection of neutrons from a helium surface has been observed for the first time. The ⁴He surface is
 smoother in the superfluid state at 1.54 K than in the case of the normal liquid at 2.3 K. In the superfluid state
 we also observe a surface layer ~200 Å thick which has a subt...

description The reflection of neutrons from a helium surface has been observed for the first time. The ⁴He surface is
 smoother in the superfluid state at 1.54 K than in the case of the normal liquid at 2.3 K. In the superfluid state
 we also observe a surface layer ~200 Å thick which has a subtly different neutron scattering cross-section,
 which may be explained by an enhanced Bose–Einstein condensate fraction close to the helium surface. The
 application of neutron reflectometry described in this paper creates new and exciting opportunities for the
 surface and interfacial study of quantum fluids.
