Measurements of element composition of impurity-helium solid phase.

[In Russian. / En russe.]


For "dry" (extracted from liquid helium) samples, the stoichiometric ratio is measured, when impurity centers were neon, argon and nitrogen. The results obtained suggest that the novel solid phase consists mainly of helium and the values of stoichiometric ratio = 12-17 measured for nitrogen and neon are close to predicted ones for the well-packed mono-layer helium spheres. Some evidence in favour of the possibility of the liquid impurity-helium Van-der-Waals phase existence at the temperatures near the temperature of the sample decomposition is obtained too.
