English[edit]
Noun[edit]
delayed neutron (plural delayed neutrons)
- (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).
