Spontaneous fission (SF) is a form of radioactive decay that is found only in very heavy chemical elements. The nuclear binding energy of the elements reaches its maximum at an atomic mass number of about 56 (e.g., iron-56); spontaneous breakdown into smaller nuclei and a few isolated nuclear particles becomes possible at greater atomic mass numbers. WebPrevious lectures pointed out that fission rate is highest for thermal neutrons (<0.01 eV). This lecture will: 1. Explain process of how 1MeV fission neutrons slow down to <0.01 eV with/without resonance capture 2. Explain energy transfer via elastic neutron collisions 3. Explain effect of moderator atomic mass (A) on rate of neutron ...
