Abstract
The reversibility of the electric response induced by second sound in helium II, the so-called “reverse effect”, was examined. Two different cylindrical cavities were used to provide a different direction of the electric field and to check the significance of the interruption of longitudinal flow from the copper mesh electrode. The ability to reproduce the normal electric response induced by second sound was verified and compared with a previously performed experiment. No indications of the reverse effect were found. The results show that the reverse effect was absent or within a lower limit of the measurement in the order of nano-volts regardless of temperature.
