Coulomb and other barriers…….!!! Neutrons vs. charged particles. HW 1 Nuclear Reaction Energetics (revisited)

Nuclear Reactor Theory, JU, First Semester, (Saed Dababneh). 8 Nuclear Reaction Energetics (revisited) The double valued situation occurs between T Th and the upper limit T a \. Double-valued in a forward cone. HW 1 (continued)

Nuclear Reactor Theory, JU, First Semester, (Saed Dababneh). 9 Discuss thoroughly the 7 Li(p,n) reaction. During the discussion emphasize on the case when the incident proton beam is 30 keV above the threshold. Use your computing skills. Nuclear Reaction Energetics (revisited) HW 1 (continued) elastic inelastic scattering neutrons Discuss the elastic and inelastic scattering of neutrons using these relations.
