Abstract
An experimental study has been made of the use of radioactive materials in preparing defects in solids. Paramagnetic resonance was used to study such defects. The systems studied utilized tritium and krypton 85. Solid tritium was studied at 4.2°K. It was found that atomic tritium was formed and showed a characteristic hyperfine splitting of 543 gauss. The krypton 85 was also studied at 4.2°K. This should yield atomic rubidium but no paramagnetic resonance characteristic of this atom was found.
