Resonance phenomenon

Japanese: 共鳴現象 - きょうめいげんしょう
Resonance phenomenon

…Fermi also discovered that nuclear reactions are highly likely to occur when the energy of the neutrons is approximately equal to a discrete value. This phenomenon is called resonance, and the reason for this is that at these energies, the incident neutron and the target atomic nucleus combine during the reaction to form a metastable, complex compound nucleus. The concept of compound nuclei was proposed by NHD Bohr in 1936 and is one of the important pillars of nuclear reaction theory. …

…フェルミはまた,中性子のエネルギーがとびとびのある値にほぼ等しいときには,核反応がきわめて起こりやすいことを見いだした。この現象は共鳴現象と呼ばれているが,共鳴現象が起こる理由は,これらのエネルギーでは,入射中性子と標的である原子核とが反応の途中で一体になって,準安定で複雑な複合核を形成することにある。この複合核の概念はN.H.D.ボーアによって36年に提唱されたもので,核反応理論の重要な柱の一つとなっている。…
