34. Investigation of Shell Effect Damping in Nuclear Fission Using VAMOS and PISTA

Theodore Efremov (CEA)

21/09/2026 10:25

Oral Presentation

Studying nuclear fission provides insight into the interplay between the dynamic evolution of the compound nucleus and microscopic effects such as shell structure and pairing correlations. Measuring fission fragment yields not only advances our understanding of nuclear structure but also has important applications in nuclear reactor physics.

This work focuses on the evolution of fission...

90. Fission studies at the ISOLDE Solenoidal Spectrometer

Maria Vittoria Managlia (Chalmers University of Technology)

22/09/2026 11:35

Oral Presentation

Nuclear fission remains a major challenge for both experimental and theoretical
studies due to its complexity, involving the collective motion of all nucleons
within a heavy nucleus. In this presentation, a novel experimental approach for
determining a key property of a nucleus, the fission barrier, is discussed.
The heavy radioactive ion beams of interest are provided by the...

10. Isotopic fission fragments yields in the Thorium region produced in inverse-kinematics with a 232Th beam

Alex Cobo Zarzuelo (GANIL)

22/09/2026 11:55

Oral Presentation

Despite the development of different theoretical models [1] and simulation codes based on experimental data, such as GEF [2], the fission process is not reproduced with enough accuracy along the nuclear chart. Given that the fission mechanism is sensitive to the interplay between both microscopical quantities, such as nuclear structure of the fission fragments, and macroscopic effects; a fully...

28. Isotopic yield distributions of transfer-induced fission from 238U on light targets

Beatriz Errandonea (IGFAE and Dpt. de Física de Partículas, Univ. of Santiago de Compostela, E-15758, Santiago de Compostela, Spain)

22/09/2026 12:15

Oral Presentation

The interplay between macroscopic liquid-drop properties and microscopic effects represents a fundamental challenge in nuclear fission [1]. This competition can be probed through excitation-energy distributions, as experimental evidence shows a systematic attenuation of structure-dependent effects, thereby progressively revealing the underlying macroscopic component of the potential-energy...

41. Evolution of the fission fragment angular momentum

Katarzyna Mazurek (Institute of Nuclear Physics PAN)

22/09/2026 12:35

Oral Presentation

This study [1] explores the role of nucleon exchange for the generation of the fission fragment angular momenta. For a number of typical fission cases, samples of 10,000 shape evolutions are generated by Langevin simulation [2] and, subsequently, for each such evolution, the nucleon exchange transport theory previously developed for damped nuclear reactions [3] is used to obtain the...

42. Probing fission fragments spin distribution from $^{238}U + ^{9}Be \rightarrow ^{247}Cm$ using AGATA & VAMOS++

J. Bequet (GANIL)

22/09/2026 12:55

Oral Presentation

Nuclear fission remains a complex quantum many-body process in which several fundamental properties are not yet fully understood. In particular, the origin of the angular momentum of fission fragments is still under debate. Recent experimental results tentatively probed the angular momentum at scission from the measurement of the spin distributions of fission fragments [1]. Their...

64. Fission studies at ISS

Anna Kawecka (Chalmers University of Technology)

Invited Presentation (Only for invited speakers)

Nuclear fission is a key process in both nuclear structure studies and astrophysical nucleosynthesis. In particular, fission influences the production of the heaviest nuclei in the rapid neutron-capture (r-) process by limiting the maximum mass that can be reached. However, experimental information on the fission barriers of neutron-rich nuclei remains limited. Measurements of fission...
