Event-by-event neutron–photon multiplicity correlations in 252Cf(sf)

摘要: Abstract Excited nuclear fragments are emitted during fission. The de-excitation of these fission takes place as sequential emission neutrons followed by photons. Correlations between neutron and photon multiplicities accompanying is thus expected. Fission event generators based on established statistical physics models predict negative event-by-event correlations in neutron–photon multiplicity. A survey published experimental results an covariance the following spontaneous 252Cf presented. Analytic unfolding expressions developed this work to determine bias introduced background sources, particle misclassification, pulse pileup, inelastic production. data re-analyzed using techniques found be qualitative agreement with predictions model-based calculations. In particular, we have concluded that there exists a significant competition 252Cf.
