Status of JENDL Photonuclear Data File and Intercomparison with Other Libraries

The Japan Atomic Energy Research Institute (JAERI) Nuclear Data Center has started evaluation work in cooperation with Japanese Nuclear Data Committee (JNDC) to produce a JENDL Photonuclear Data File. The JENDL Photonuclear Data File is provided for applications such as electron accelerator shielding and radiation therapy, and given for gamma-ray induced reactions up to 140 MeV. The photon absorption cross section is evaluated with the giant dipole resonance model and the quasi-deuteron model, and the decaying processes are estimated with the statistical model with preequilibrium correction by using MCPHOTO and ALICE-F codes. The intercomparison has been made of JENDL Photonuclear Data File with other evaluated photonuclear data files such as BOFOD, CNDC, EPNDL, and LANL as well as experimental data available for the important elements.
