摘要

The water-helium condensate (watergel) is formed in He-II cooled below 1.5 K as a result of condensation of the gas flow of He-4 with the water impurity at the surface of superfluid liquid. The experimental results indicate that the shape of the gel samples formed below the liquid surface depends strongly on geometry of experimental cell: from an oval iceberg in a narrow glass tube (9 mm. in inner diameter) to vertically arrange clouds in a wide cell (30 mm in diameter). From our estimations it follows that the total content of water in bulk of the get samples is less than 10(20) molecules/cm(3) and that their density is a few percent higher than the density of surrounding liquid only.
