Neutron Reflection from the Surface of Liquid 4He with and without a Layer of 3He
T. R. Charlton, R. M. Dalgliesh, A. Ganshin +3
We report and discuss the first neutron reflection measurements from the free surface of normal and superfluid 4He and of liquid 3He-4He mixture. In case of liquid 4He the surface…

Neutron reflection from the surface of normal and superfluid 4He
T. R. Charlton, R. M. Dalgliesh, A. Ganshin +3
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…
