| Abstract: | A density increase of He II up toΔρ/ρ=3·10?4 due to turbulent flow caused by a heat current in a wide tube has been observed by pycnometric measurements and by measuring the dielectric constant of He II. The state of increased density appears to be metastable against mechanical disturbances. |
