摘要

Impurity-Helium solids are highly porous van der Waals solids made up of impurity atoms, molecules. or clusters of atoms and molecules surrounded by thin layers of solid helium. The results of structural investigations via ultrasound and X-ray diffraction are reported. Preliminary nuclear magnetic resonance measurements on D, impurities in these solids are discussed. Recent electron paramagnetic resonance experiments have explored exchange tunneling reactions in the Impurity-Helium solids. In particular, when D atoms are introduced into an Impurity-Helium solid containing H,. the concentration of H atoms is observed to increase. possibly as a result of the reactions D + H-2 --> H + HD and D + HD --> H + D-2.
