It is shown that the formation of a bound roton-ion state in superfluid helium is possible for arbitrarily weak attraction. An equation for the energy spectrum of the bound states and its solutions for a zero total momentum of the compound quasiparticle are obtained on the basis of the roton-ion interaction potential found previously. The momentum dependence of the binding energy near the end points of various branches of the spectrum is found. The problem of experimental observation of the phenomena is discussed.
