79. Transfer reactions for nuclear astrophysics studies (present and future)

Fairouz HAMMACHE (IJCLab Orsay)

22/09/2026 17:20

80. Theoretical nuclear uncertainties and their impact on astrophysical predictions

Stephane Goriely (Université Libre de Bruxelles)

22/09/2026 17:45

Invited Presentation (Only for invited speakers)

Despite major advances over recent decades, the origin of the elements heavier than iron
remains debated and is not yet fully resolved. In particular, our understanding of the
nucleosynthesis processes is still affected by relatively large nuclear uncertainties. Given the
extreme scarcity of experimental reaction and decay data for the many unstable nuclei
involved in nucleosynthesis...

40. Core deformation in weakly-bound exotic nuclei and the transfer to the continuum of 17C

JOSE ANTONIO LAY VALERA (Universidad de Sevilla)

22/09/2026 18:10

Oral Presentation

The study of reactions involving weakly bound exotic nuclei is an active field due to advances in radioactive beam facilities. Many of these nuclei can be approximately described by a model consisting of an inert core and one or more valence nucleons. However, to properly describe some of these nuclei within few-body models, additional effects must be considered, such as deformations and...

4. 12Be structure study via resonant elastic scattering with ACTAR TPC

Lou Dienis (GANIL - Université de Caen Normandie)

22/09/2026 18:30

Oral Presentation

The ¹²Be nucleus lies far from the valley of stability in the neutron-rich region of the beryllium isotopes. As a light exotic nucleus exhibiting a breakdown of the classical magic number N = 8, ¹²Be provides a valuable testing ground for exploring the interplay between shell evolution, clustering, and deformation.

The structure of ¹²Be was investigated through the resonant elastic...

48. Universal Few-Body Correlations in Four-Particle Halo Structures: Application to Carbon-22

Dr Rafael Francisco (Laboratoire De Physique Des 2 Infinite Irène Joliot-Curie)

22/09/2026 18:50

Oral Presentation

Halo nuclei, where weakly bound nucleons extend far beyond a compact
core, offer a unique window into universal few-body physics near the
limits of nuclear stability. Their properties are controlled by
low-energy parameters, such as separation energies, scattering lengths
and correlations among the valence particles, making them ideal
benchmarks for testing universality in nuclear...
