Abstract

This paper gives a brief description of the library of evaluated cross sections for the activation reactions (n,2n), (n,3n), (n,p), (n,np), (n,α), (n,nα), (n,d), (n,t), (n,γ) for 645 stable and long-lived (> 10 hours) radioactive nuclei having atomic masses in the range 1–210 (hydrogen to polonium) and in the range of neutron energies from the threshold for the given nucleus to 20 MeV. The evaluated cross sections were obtained by analysing available experimental data and theoretical excitation functions from other activation libraries using the similarity method and empirical systematics of threshold reaction excitation functions.

Keywords
neutron data, threshold reaction cross section, excitation functions, empirical systematics.
