Overview

Photo-induced reaction cross section data are of importance for a variety of current or emerging applications, such as radiation shielding design and radiation transport analyses, calculations of absorbed dose in the human body during radiotherapy, physics and technology of fission reactors (influence of photo-reactions on neutron balance) and fusion reactors (plasma diagnostics and shielding), activation analyses, safeguards and inspection technologies, nuclear waste transmutation, medical isotope production and astrophysical applications.
A new Evaluated Photonuclear Library PD-2019 was produced by the IAEA Coordinated Research Project (CRP). Extensive experimental measurements were also undertaken under the project which was of great help for new evaluations. In particular, collaboration measurements undertaken at the LCS NewSUBARU facility (Laboratory of Advanced Science and Technology for Industry, University of Hyogo, Japan) were critical for the success of the project. Both experimental and evaluation efforts carried out within the CRP to update the IAEA Photonuclear Data Library are explained in Kawano et al., Nuclear Data Sheets 163 (2020) 109-162. The new library includes 199 mostly new evaluations, 20 evaluations were retained from the previous 1999 IAEA Photonuclear Data Library (IAEA/PD-1999).

ENDF-6 formatted library

The library contains evaluated photonuclear data for 219 isotopes for incident photons (gamma rays) with energies mostly up to 200 MeV. The list of the files are available here. The library includes cross sections and emission spectra in ENDF-6 format. The file format description is explained in the report IAEA-NDS-0232. The ENDF-6 formatted individual evaluations are available at IAEA Github site. The complete ENDF-6 library can be downloaded as a compressed (tgz) archive under the following link:

IAEA Photonuclear Data Library 2019 (ENDF-6) (iaea-pd2019.tar.gz)

To untar the files, use the command tar -zxvf filename.tar.gz on Unix or MacOS.

Derived transport libraries

The production of application libraries from the ENDF-6 formatted files was undertaken at the IAEA Nuclear Data Section. ACE-formatted files were produced with ACEMAKER, which is able to take into account all the new features present in the IAEA-PD2019 ENDF files as described in this report. The files are also available individually from the IAEA Github site. It is expected that the files will be usable by MCNP versions later than 6.2.

A number of 56 transport files above have been extended to include additional information. For eight actinides delayed neutron data and for 48 materials dosimetry/production data has been added.

Derived activation libraries

An activation library prepared at the IAEA Nuclear Data Section by H. Kawada (Tokyo Institute of Technology, Japan), J.-Ch. Sublet and S. Okumura (IAEA), and T. Kawano (LANL, USA), is described in the report on "Processing of the Evaluated Photonuclear Data Library (IAEA-PD2019)" available as IAEA-NDS-0232. The processed activation files can be also retrieved from the IAEA Github as individual files (*.endf, *.pdf, etc) and tar compressed file (*.tar.gz) as follows.
