S Leoni, C Michelagnoli, JN Wilson - La Rivista del Nuovo Cimento, 2022 - Springer
The paper reviews recent developments in γ-ray spectroscopy of the neutron-rich fragments
produced in nuclear fission. This subject has been an intensive area of study spanning more …

Heavy-element fission barriers

P Möller, AJ Sierk, T Ichikawa, A Iwamoto… - Physical Review C …, 2009 - APS
We present calculations of fission properties for heavy elements. The calculations are based
on the macroscopic-microscopic finite-range liquid-drop model with a 2002 parameter set …

Fission barriers at the end of the chart of the nuclides

P Möller, AJ Sierk, T Ichikawa, A Iwamoto… - Physical Review C, 2015 - APS
We present calculated fission-barrier heights for 5239 nuclides for all nuclei between the
proton and neutron drip lines with 171≤ A≤ 330. The barriers are calculated in the …

Yields of correlated fragment pairs in spontaneous fission of Cf

GM Ter-Akopian, JH Hamilton, YT Oganessian… - Physical Review C, 1997 - APS
Independent yields of 139 individual secondary (appearing after neutron evaporation)
fragment pairs of five different charge splits (ZL/ZH= 46/52, 44/54, 42/56, 40/58, and 38/60) …

A study of probable alpha-ternary fission fragments of 257Fm

HC Manjunatha, N Sowmya, KN Sridhar… - … of Radioanalytical and …, 2017 - Springer
The probable α-accompanied cold ternary fission fragments of 257 Fm are studied using six
types of nuclear proximity potentials. We have studied the driving potential, probability …

Third minima in thorium and uranium isotopes in a self-consistent theory

JD McDonnell, W Nazarewicz, JA Sheikh - Physical Review C—Nuclear …, 2013 - APS
Background: Well-developed third minima, corresponding to strongly elongated and
reflection-asymmetric shapes associated with dimolecular configurations, have been …

Multicluster accompanied fission

DN Poenaru, W Greiner, JH Hamilton, AV Ramayya… - Physical Review C, 1999 - APS
In this process a heavy or superheavy nucleus spontaneously breaks into four, five, or six
nuclei of which two are asymmetric or symmetric heavy fragments and the others are light …

Manifestation of clustering in the 252Cf (sf) and 249Cf (nth, f) reactions

YV Pyatkov, VV Pashkevich, YE Penionzhkevich… - Nuclear Physics A, 1997 - Elsevier
A comparative analysis of the high-statistics mass-energy distributions of the fission
fragments formed in the 252Cf (sf) and 249Cf (nth, f) reactions is performed on the basis of …

Realistic fission saddle-point shapes

P Möller, A Iwamoto - Physical Review C, 2000 - APS
A realistic determination of fission saddle-point shapes requires an exploration of a
sufficiently large deformation space so that all a priori reasonable candidates for saddle …

Scission configurations and their implication in fission-fragment angular momenta

L Bonneau, P Quentin, IN Mikhailov - Physical Review C—Nuclear Physics, 2007 - APS
The generation of sizable angular momenta in fragments formed in low-energy nuclear
fission is described microscopically within the general quantum-mechanical framework of …
