✦ Synopsis

Rotons and impurities such as ions or solvated 3He particles can interact via dipolar forces from the flow fields of the roton and the motion of the impurity through the background fluid. Stable bound states of rotons to impurities can occur with near-zero total momentum. We give explicit results of bound-state calculations for solvated 3He, the positive helium ion, and the negative electron bubble.

The cross section for light scattering from superfluid helium in which bound roton pairs are created is calculated in a simple model, taking into account both the excitations themselves and their coupling to the light. It is shown that the depolarization ratios from bound and from noninteracting rot

Bound states and scattering resonances for a 3He-vacancy system in crystalline 4He are shown to exist. For realistic physical parameters the theory yields binding energies of ~ O. 1 K. It is found that the bound states and scattering resonances tend to enhance the diffusion coefficient of 3He. The e
