Reference no: EM13658898

Neutrons released by a fission reaction must be slowed by collisions with the moderator nuclei before the neutrons can cause further fissions. Assume a 1.3 MeV neutron leaves each collision with 66 percent of its incident energy. Determine how many collisions are required to reduce the neutron's energy to at least 0.040 eV, find which is the energy of a thermal neutron?
