abstract
We describe a method of combining the stabilization of impurities in superfluid helium and magnetic resonance techniques to study hyperfine resonance in atomic deuterium obtained by passing a D2-He mixture through a radiofrequency discharge. The resulting D-D2-He gas mixture penetrates a superfluid helium surface and forms a Van der Waals solid mixture containing atoms of D and He as well as D2 molecules. In preliminary experiments we have applied magnetic resonance (309 MHz) to the - transition to study spin-spin and spin-lattice relaxation in atomic deuterium and to provide information about the surroundings of atomic deuterium isolated in the D-D2-He solid.
