There is a renewed interest in photonuclear reactions for various applications such as radioactive ion beam or neutron production, waste transmutation and detection of nuclear materials. However, contrary to the neutron induced reactions, evaluated nuclear data files for photons contain little information, especially for incident energies above 20 MeV. From a physics point of view, gamma induced reactions allow to study nuclear reaction mechanisms for some compound nucleus hardly available with a direct neutron probe. This paper gives an overview of our on-going activities on photonuclear data evaluation of uranium and thorium isotopes. |
