Abstract—Curves describing the liberation of helium from Sn single crystals deformed by stretching in liquid
3He and 4He and from Cd polycrystals in 4He are analyzed. It is found that the stress–strain diagrams for Sn are
in qualitative agreement with the concentration of helium in the samples. The peaks in the amount of He liber-
ated from Cd and Sn at temperatures both below and above the melting point are found to be of different types.
The reasons for this difference are investigated, and the assumption concerning the existence of a chemical bond
between helium atoms and structural defects of the metals under investigation is formulated. © 2002 MAIK
