Rotons and impurities such as ions or solvated /sup 3/He 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 /sup 3/He, the positive helium ion, and the negative electron bubble.
