noun

Meanings

  1. 1 prompt neutron (nuclear physics: a neutron emitted within roughly 10⁻¹⁴ s of a fission event, as opposed to a delayed neutron)

Examples

Shùnfā zhōngzǐ zài lièbiàn hòu lìjí fàngchū.
Prompt neutrons are released immediately after fission.
Shùnfā zhōngzǐ hé huǎnfā zhōngzǐ shì fǎnyìngduī kòngzhì de guānjiàn.
Prompt and delayed neutrons are key to reactor control.

Tips

usage
Pairs with 中子 (huǎnfā zhōngzǐ, 'delayed neutron'). Reactor stability depends on the small fraction of delayed neutrons — without them, control rods would be too slow to react.
