Neutron Activation - General

This page includes evaluated data files for neutron activation cross-sections for general use. See also Neutron Activation for Dosimetry and Thermal Neutron Activation Cross Sections.

RNAL- Reference Neutron Activation Library

Evaluated data for 255 important neutron-induced reactions leading to radioactive products, selected from various libraries and reformatted to ENDF-6 format. The full library, individual reactions and comparison plots with experimental data from EXFOR are available online or on CD-ROM.

FENDL/A-2.0

Comprehensive neutron cross section library for 13006 neutron activation reactions with 739 target nuclides from H to Cm in the incident energy range up to 20 MeV, for fusion (and other) applications. The data are in ENDF format with some modifications. Compared to the previous version FENDL/A-1.1, many nuclides and reactions were added or revised. The evaluations were selected from major activation libraries including EAF-4.1, ADL-3, JENDL/A-3.2 and others. Available on magnetic tape or by FTP or WWW file transfer.
Summary documentation: IAEA-NDS-173. Plots of the FENDL/A-2.0 activation cross sections in comparison with experimental data retrieved from EXFOR are available online. Interactive plotting with the ZVView package is provided.

FENDL/A-2.0 Processed Files

(FENDL2/A-MCNP, FENDL2/A-VITJ_E, FENDL2/A-VITJ_FLAT). Pointwise cross sections (any resonance parameters contained in the original data files were converted to cross sections) for 13006 activation reactions for 739 target nuclides (including metastable states), processed for use with the Monte Carlo neutron/photon transport code MCNP, and as VITAMIN-J 175 multigroup data weighted with the VITAMIN-E neutron weighting spectrum and with a constant (flat) weighting spectrum. Available on magnetic tape or by FTP or WWW file transfer.
Summary documentation: IAEA-NDS-174.

UENDL/NAA

USSR Evaluated Nuclear Data Library for Neutron Activation Analysis of 1988, by V.M. Bychkov et al. It contains recommended values for activation cross-sections of 14,5 MeV energy neutrons and neutrons from U-235 and Cf-252 fission; for resonance integrals of capture, aborption and fission reactions; for thermal neutron capture and absorption reaction cross-sections; for effective resonance energy values; for the main gamma-ray energies of neutron capture and for their absolute intensities; for half-lives and abundance for all known nuclides. Available on a set of two low density PC diskettes.
Documentation: IAEA-NDS-125 by A.B. Pashchenko.

ACTIV87

Fast Neutron Activation Cross-Section File by V.N. Manokhin, A.B. Pashchenko, V.I. Pljaskin, V.M. Bychkov, V.G. Pronjaev. This library contains evaluated cross-sections for 206 important fast- neutron induced activation reactions in the energy range from threshold up to 20 MeV. This file contains the numerical data of the graphical plots that had been published in the IAEA Handbook on Nuclear Activation Data (K. Okamoto, ed.), IAEA Technical Report 273 (1987), pp 305-411. A brief documentation of this data library is given in the report IAEA-NDS-96 (O. Schwerer, ed.).
