Abstract
The influence of a fermionic impurity on the spectrum of overcondensate excitations of a superfluid Bose system is investigated. The scattering of neutrons on the Bose condensate of a superfluid 4He and a mixture of the liquid 3He and 4He is considered. An analytic expression for the spectrum of overcondensate excitations for these two systems is found. Bibliography: 10 titles.
