    Does a Universal Neutron Range Graph Exist for Various Materials?

    Hello everyone, Is there such a thing as range graph as a function of the energy for the neutrons in matter? I have been looking for it all over the web, but I just found the cross sections plotted when the neutron comes from different reactions. Is there a more general graph that discribes the...
