8. Collision between neutrons and nucleus of the moderator results in slowing down the newly born fast neutrons. Such a collision is depicted in the figure. The striking fast neutron has an initial energy En and an initial momentum pa. The tar- get nucleus is initially at rest. Considering an elastic scattering, following the col- lision, the scattered neutron has an energy of E, and momentum of p, while the recoiling nucleus has an energy of Ey and momentum of py. Use the conserva- tion of momentum and energy to drive a relation for energy of the scattered neu- tron in terms of the initial neutron energy and mass number of the target nucleus. [Hint: Find the momentum of the recoiling nucleus in terms of the momentum of the initial and the scattered neutron. Substitute for momentum terms (p = 2mE) and for the recoiling energy from the energy balance]. Scattered Neutron E, Pa EN Striking Target Pa Neutron Nucleus Recoiling Nucleus PN
