Prompt fission gamma-ray observables depend on the angular momenta of fission fragments (FFs). However, as neutron emission is much faster than gamma emission, extraction of FF spin properties can be subject to uncertainties due to the corrections for neutron emission. For example, in FREYA and CGMF, two simulation codes modeling the prompt neutron and gamma emissions from FFs, the neutron...

Angular momenta in fission can be discussed at different time steps of the process for different systems: incoming particle, target nucleus, compound nucleus at saddle, at scission for both nascent fission fragments, fission fragments before neutron emission, after...

The fission simulation model FREYA is well suited for studying the role of angular momentum in fission because it obeys all conservation laws, including linear and angular...
