Zusammenfassung:The capillary turbulence on the surface of normal and superfluid liquid He has been studied experimentally. It is observed for the first time that the value of the high-frequency boundary omega b of the inertial interval increases significantly when liquid helium transits from normal to superfluid state, and that in superfluid He-II the correlation function of the surface deviation from equilibrium state in frequency representation can be described well by a power dependence with the index m close to -4.3.
