The GEF (“GEneral description of Fission observables”) model code is documented. It
describes the observables for spontaneous fission, neutron-induced fission and, more …

“Trust is the greatest incentive. If trust is missing, everything is missing.”[Maria Theresia
(1717–1780), Empress of Austria] If nuclear data users do not trust the data provided by data …

Background: The role of angular momentum in fission has long been discussed but the
observable effects are difficult to quantify. Purpose: We discuss a variety of effects …

Improved knowledge of prompt emission in fission has significant implications for our
understanding of the fission process. It is also important for improving nuclear data …

A series of experiments has been performed to measure prompt neutron angular and energy
distributions from thermal neutron-induced fission of 235,233 U in correlation with the fission …

Neutrons and photons are characteristically emitted during the nuclear fission process when
a deformed, neutron-rich nucleus divides into two fragments that then deexcite. During …

A twin position-sensitive Frisch grid ionization chamber, intended as a fission fragment
detector in experiments to study prompt fission neutron correlations with fission fragment …

We present new results on neutron and gamma-ray pulse-height distributions (PHDs)
measured with liquid scintillators from five plutonium-oxide samples of varying mass and …

Angular and energy distributions of prompt neutrons from the spontaneous fission of 252 Cf
have been measured. The yield of “scission” neutrons has been estimated by comparing the …

Background: Spontaneous fission events emit prompt neutrons correlated with one another
in emission angle and energy. Measurements of these correlations can shed light on the …
