FISPACT-II comes with a suite of nuclear data libraries, including:

- Groupwise cross section data [xs, with incident particles n,p,d,g,a,t,h]
- Radioactive decay data [decay]
- Fission yield data [fy (neutron-induced, spontaneous and non-neutron-induced)]
- Self-shielding probability tables [pts]

A range of different evaluations are available for each of these data types, and FISPACT-II is distributed with the best, and most recent, evaluations from around the world. For each group cross section library, multiple temperatures may be available. Typically, these include 293 K, 600 K and 900 K, with associated self-shielding probability tables. In addition, multiple energy group discretisations are available for a selection of libraries, including the CCFE 709 and 162 groups, UKAEA 1102 and CASMO 586. You can download these from the links below.

**For Release 4.0, the standard library package includes:**

**Data download for SPECTRA-PKA**

SPECTRA-PKA is a command-line driven programme for calculating the expected primary knock-on atom (PKA) spectra for a given target nuclide under neutron or charged particle irradiation. See the wiki for more details. SPECTRA-PKA uses NJOY-generated recoil cross section matrices. An evolving selection of databases produced using various international reaction cross section libraries (for various incident particle types) have been pre-calculated and are available to download as compressed tar archives from:
