Impact of pear-shaped fission fragments on mass-asymmetric fission in actinides

G Scamps, C Simenel - Nature, 2018 - nature.com
Nuclear fission of heavy (actinide) nuclei results predominantly in asymmetric mass splits.
Without quantum shell effects, which can give extra binding energy to their mass-asymmetric …

Evolution of Octupole Deformation in Radium Nuclei from Coulomb Excitation of Radioactive and Beams

PA Butler, LP Gaffney, P Spagnoletti, K Abrahams… - Physical review …, 2020 - APS
There is sparse direct experimental evidence that atomic nuclei can exhibit stable “pear”
shapes arising from strong octupole correlations. In order to investigate the nature of …

Effect of shell structure on the fission of sub-lead nuclei

G Scamps, C Simenel - Physical Review C, 2019 - APS
Fission of atomic nuclei often produces mass asymmetric fragments. However, the origin of
this asymmetry was believed to be different in actinides and in the sub-lead region …

Pear-shaped atomic nuclei

PA Butler - Proceedings of the Royal Society A, 2020 - royalsocietypublishing.org
This review presents the current status of experimental evidence for the occurrence of
reflection-asymmetric or 'pear'shapes in atomic nuclei, which arises from the presence of …
