Status of nuclear data evaluation for JENDL Photonuclear Data File

For γ-ray induced reaction data up to 140 MeV, The JENDL Photonuclear Data File is provided for applications such as electron accelerator shielding and radiation therapy. The file will include the photonuclear reaction data for 29 elements (50 isotopes) from 2H to 238U. The photon absorption cross-section is evaluated with the giant dipole resonance model and quasi-deuteron model, and the decaying processes are estimated with the statistical model with preequilibrium correction by using MCPHOTO and ALICE-F codes. The evaluation work is now in a final stage. The present status of the Photonuclear Data File is reviewed in this paper. (author)
