Reference Neutron Activation Library

RNAL is a library of evaluated cross sections for neutron induced reactions leading to radioactive products.

These reactions are used in various applications, especially in the activation analysis. The evaluations have been selected from various national and regional projects and assembled at IAEA Nuclear Data Section.

The library is restricted to the 255 most important reactions. The relatively small number of reactions allowed for a detailed assessment of the library providing the user with the information on the quality of the data.

The original evaluations were reformatted to conform to the ENDF-6 standard. All Q-values and thresholds were consistently recalculated using recent recommended masses of Audi-Wapstra 95 and isomer energies taken from NUDAT.

The library was checked using CHECKR, FIZCON and PSYCHE codes, which produced no messages that would raise serious concern.
