delayed neutron

英語（米国） (en-US) 英語（イギリス） (en-GB)

名詞

(nuclear physics) A neutron produced as a result of nuclear fission which is emitted upon the radioactive decay of a fission product nucleus seconds to minutes later, rather than at the time of the initial fission event. Less than 2% of fission neutrons are delayed neutrons (the exact proportion depends on the nuclide being fissioned).

日本語の意味

核分裂反応によって作られた中性子のうち、初期の核分裂の際には放出されず、核分裂生成物の原子核が放射性崩壊を起こすことによって、数秒から数分後に放出される中性子を指す。 / 全核分裂中性子の中で、約2%未満であり、その割合は反応対象の同位体に依存する。
