English Dictionary

prompt neutron

名詞

(nuclear physics) A neutron produced immediately by the fission of an atomic nucleus, instead of being emitted by decaying fission products seconds to minutes later; over 99% of all fission neutrons are prompt neutrons (the exact proportion depends on the nuclide undergoing fission).

日本語の意味

原子核分裂により即座に生成される中性子。核分裂直後に放出され、通常は数秒から数分後に放出される遅発中性子と区別される。

A single prompt neutron from a fission event can significantly affect the reactor's neutron population if conditions are near critical.

原子核分裂で直ちに生成される単一の中性子は、状態が臨界に近い場合、原子炉の中性子数に大きな影響を与えることがある。
