The JANIS Books are compilations of cross-section curves of evaluated and experimental data from a number of evaluated libraries, nuclear reactions and associated reaction products. JANIS Books are available for nuclear reactions induced by neutrons, photons and light-charged particles.
Online JANIS Books are up-to-date interactive versions that allow the users to zoom, access complementary information and plot additional data.
JANIS Books are available for download in PDF format. The PDF version contains tables of simple integral neutron cross-section data for the main reaction channels, as well as tables of reaction Q values for residual production cross-sections. More information is provided in each of the following Books:
