Theory of nuclear fission
Atomic nuclei are quantum many-body systems of protons and neutrons held together by
strong nuclear forces. Under the proper conditions, nuclei can break into two (sometimes …

Angular momentum in fission fragments
T Døssing, S Åberg, M Albertsson, BG Carlsson… - Physical Review C, 2024 - APS
We suggest that the angular momentum in fission fragments is generated by statistical
excitation at scission. The magnitude of the angular momentum is determined by excitation …
