Photonuclear data evaluations of actinides up to 130 MeV

There is a renewed interest in photonuclear reactions for various applications such as active nuclear material detection techniques and radioactive ion beam or neutron production targets. However, contrary to the neutron induced reactions, evaluated nuclear data libraries contain little information for photons. In particular, there are very few photonuclear data evaluations of actinides above 20 MeV. This paper gives an on-going evaluation activity for 232Th, 235U, 238U and 239Pu. Photonuclear cross sections up to 130 MeV were calculated with the latest version of the TALYS code using a deformed optical potential by Soukhovitskii to model the neutron emission. The fission transmission coefficients were calculated using a double humped barrier model. Fission barriers heights and widths were adjusted in order to reproduce experimental data.
