Manipulation of solid-liquid interface of ⁴He by acoustic radiation pressure
Acoustic radiation pressure is thought to be very useful for solid ⁴He experiment under the microgravity. We observed that solid-liquid interface of ⁴He was manipulated by the acoustic wave. We applied the sound pulse perpendicularly to the flat interface between two transducers. The interface moved...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Acoustic radiation pressure is thought to be very useful for solid ⁴He experiment under the microgravity. We observed that solid-liquid interface of ⁴He was manipulated by the acoustic wave. We applied the sound pulse perpendicularly to the flat interface between two transducers. The interface moved to the sound direction at low temperatures. We also checked how the interface moved when sound was applied parallel to the interface. Dynamics of the interface during and after the sound pulse were recorded by a high speed CCD camera.
