Theory of nuclear fission

N Schunck, D Regnier - Progress in Particle and Nuclear Physics, 2022 - Elsevier
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 …

Nucleosynthesis and observation of the heaviest elements

Microscopic analysis of induced nuclear fission dynamics

ZX Ren, J Zhao, D Vretenar, T Nikšić, PW Zhao, J Meng - Physical Review C, 2022 - APS
The dynamics of low-energy-induced fission is explored using a consistent microscopic
framework that combines the time-dependent generator coordinate method (TDGCM) and …

Fission fragment intrinsic spins and their correlations

A Bulgac, I Abdurrahman, S Jin, K Godbey… - Physical Review Letters, 2021 - APS
The intrinsic spins and their correlations are the least understood characteristics of fission
fragments from both theoretical and experimental points of view. In many nuclear reactions …

Probing fission fragment angular momenta by photon measurements

J Randrup, T Døssing, R Vogt - Physical Review C, 2022 - APS
We discuss how the measurement of photon angular correlations can reveal information
about the orientation of the fission fragment angular momenta. Photons from identified …
