NEUTRON CROSS-SECTION STANDARDS, 2006

An IAEA Nuclear Data Section Initiative


DATA

This is a collection of data for standards cross sections and related quantities. The data are provided in different formats readly usable.  Some information on the evaluation procedures are found in the reference [1]. Additional information is provided in reference [2] and in the other sections of this website (see Documents and Reports pages).
