The possibility of using Compton scattered radiation to induce nuclear resonance absorption is discussed. It is shown that sufficient counting rate may be obtained with gamma ray sources now in use, if a suitably curved scattered is used. The energy spread of the secondary radiation is investigated experimentally by comparison with mono-energetic gamma rays. The method seems promising for level life-times shorter than 10 -13 sec. Energies up to 2.5 MeV may be produced, and possibly higher energies.
