✦ Synopsis

The analogy between the theory of superfluidity and the theory of dielectrics can be extended to account for some of the properties of rotons in dilute solutions of 3He in superfluid 4He. These include the normal fluid density ratio and the shifts in energy of roton excitations relative to those of pure 4He.
