6. The Physics of the CGMF Code

Patrick Talou (Stardust Science Labs)

The CGMF code generates binary fission events and follows the decay of the two scission fragments through the evaporation of prompt neutrons and photons. It implements the Hauser-Feshbach theory of nuclear reactions to follow the competition between neutron and photon emission at every stage of the decay and for every excitation energy, spin and parity the fragments are in. It is written in...

5. Shape evolution in the A≈100 region studied by fission-fragment γ-ray spectroscopy: recent progress and perspectives

Nuclear fission provides broad access to neutron-rich nuclei in the $\mathrm{A}\approx 100$ region and enables detailed $\gamma$-ray spectroscopy across the $\mathrm{N}\approx 60$ shape-transition landscape. This region is characterized by a sharp onset of deformation at $\mathrm{N}=60$ near $\mathrm{Z}\approx 38-40$, an abrupt loss of collectivity when moving to lower $\mathrm{Z}$, and an...

54. Building Continuous Potential Energy Surfaces for Nuclear Fission Dynamics

Pablo Nieto Gallego (CEA)

Nuclear fission is a complex many-body process involving a very large number of degrees of freedom. A widely used microscopic framework to describe this phenomenon is the Time-Dependent Generator Coordinate Method, where the generating functions are constrained Hartree-Fock-Bogoliubov states. In this context, elongation and mass asymmetry appear as essential collective degrees of...

56. Improved modelling of nuclear fission with the TDGCM and projection techniques

Ngee Wein Lau (Laboratoire des 2 Infinis Toulouse (IN2P3/CNRS))

The demand for an accurate, predictive model of nuclear fission continues to grow today, driven not only by the development of new experimental facilities but also by the need to describe exotic reactions relevant to stellar nucleosynthesis or superheavy element formation. However, given the complexity of the fundamental quark-gluon interactions, theoretical attempts to simulate nuclear...
