11. Fission@VAMOS/GANIL: recent results and future

SCHMITT, christelle (IPHC Strasbourg)

26/09/2023 09:00

Nuclear Dynamics

Invited presentation

Fission at low excitation energy has shown over the past decades to be an ideal playground for studying fundamental nuclear properties, in general, and dynamical aspects of nuclear reactions, in particular. While the importance of structural effects in the nascent fragments has been established through numerous studies, the VAMOS campaigns performed during the last few years definitively...

72. Gamma ray spectroscopy of nuclear fission at ALTO and NFS

Dr WILSON, Jonathan (IJC Lab, Orsay, France)

26/09/2023 09:50

Oral Presentation

Nuclear fission is a complex, dynamical process involving a dramatic re-arrangement of nuclear matter. Even after much experimental and theoretical investigations over many years this fascinating nuclear reaction is stil not fully understood due to the large number of degrees of freedom and final multitude of final states which can be populated. The gamma rays emitted in nuclear fission...

9. Shell effects in fission and quasifission

SIMENEL, Cedric (Australian National University)

Nuclear Dynamics

Oral Presentation

Fission of atomic nuclei is often affected by quantum effects leading to asymmetric mass splits. These shell effects can be investigated at the mean-field level with single particles level densities, indicating that several proton and neutron shell effects are usually at play prior to scission [1]. In addition to shell effects in the compound nucleus, quantum shells stabilising fission...

39. Energy Dependence of Prompt Fission Neutron Multiplicity in the Reaction

Dr MARINI, Paola (CENBG/CNRS)

Applications

Oral Presentation

Prompt neutron emission is a challenge in nuclear fission research. Accurate values of the number of prompt fission neutrons emitted in fission reaction and their kinetic energy distributions are essential for fundamental and applied nuclear physics. Indeed, they provide
valuable information on the amount of excitation energy of the heated fissioning system transferred to the primary...
