Compound nuclear process, Resonance and statistical property, Statistical model of nuclear reaction

Iwamoto, Osamu  

Following parts in Section 3 "Nuclear Reaction" of Chapter 1 "Nuclear Physics and Nuclear Reaction" in "Encyclopedia of Atomic Energy, Quantum, and Nuclear Fusion for Beginners" of Maruzen are written. In Subsection 4 "Compound Nuclear Process", concepts of the compound process that is the main process of low energy neutrons, which is important for atomic energy, is described. In Subsection 5 "Resonance and Statistical Property", for low energy neutron resonances, their characteristics and statistical properties such as widths and resonance spacing are described. In Subsection 6 "Statistical model in Nuclear Reaction", Hauser-Feshbach formula, which is the main theory for the compound nuclear process, is described and the physical quantities needed for the calculations are shown.
