61. New isotopes search experiments at GSI and prospective for FAIR

Prof. Stephane Pietri (GSI Helmholtzzentrum für Schwerionenforschung, Germany)

invited

By 2023 a totality of 3337 nuclides have been discovered by mankind [1] of which 445 have been discovered at GSI in its various experimental areas (FRS, SHIP, TASCA, Online Mass Separator etc..) which ranks it as a second place in worldwide discoveries. Continuing this tradition, we report in this paper of an experiment performed at the GSI in FAIR Phase-0 where new isotopes were identified...

1. Gamma-neutron program for structure nuclear and reactions with γ-ray beams at ELI-NP

Pär-Anders Söderström (ELI-NP)

contributed 15+5

The Extreme Light Infrastructure – Nuclear Physics (ELI-NP) facility is a major European nuclear physics facility for high-power laser beamlines and a projected high-brilliance γ-ray beams with energy up to 20 MeV and a very narrow bandwidth. The scientific focus of the γ beam system will cover a broad range of topics from nuclear astrophysics to applications to basic science. One of the...

High-precision mass measurements of radioactive isotopes play a key role in advancing our understanding of nuclear structure and nuclear astrophysics. Nuclear masses provide direct access to binding energies and are essential inputs for testing nuclear models and studying shell evolution far from stability. Accurate masses are indispensable for modeling nucleosynthesis pathways, such as the...

39. Physics highlights from the SEC station of HIE-ISOLDE

Olof Tengblad (Consejo Superior de Investigaciones Cientificas (CSIC) (ES))

contributed 15+5

The XT03 beamline at the HIE‑ISOLDE facility is a highly versatile station designed for a wide range of non‑permanent reaction experiments. At its focal plane, a large reaction chamber (SEC) is installed, capable of accommodating various internal detection setups. This article presents an overview of the first ten years of operation, highlighting key physics results achieved at the station.

10. Fragmentation Cross-section Measurements at FRS Using the Uranium Beam

Tuomas Grahn (University of Jyvaskyla (FI))

contributed 15+5

Projectile fragmentation is universal and very powerful tool for production of exotic nuclei, including neutron-deficient species. The yield estimates of neutron-deficient trans-Pb nuclei lack benchmark against experimental data in terms of production cross sections. Therefore, measurements of projectile fragmentation cross-sections using the 1 AGeV ²³⁸U primary beam on a...

15. Designing coincidence gamma-ray spectrometers with optimized minimum detectable activity

Elias Arnqvist

contributed 12+3

Coincidence gamma-ray spectrometers are promising detector systems in numerous circumstances, thanks to their improved minimum detectable activity (MDA) compared to conventional single-detector systems. In the field of radionuclide monitoring, coincidence gamma-ray spectrometers have the potential to lower detection thresholds and improve the ability to verify compliance with treaties that ban...

23. First measurements of the (n,Xp)Fe-nat cross sections with the Medley setup at GANIL

Light-ion emission from neutron-induced reactions remains crucial for enhancing our understanding of the theoretical models governing these nuclear reactions, as well for a wide range of practical applications. Despite advances in recent decades, models such as those implemented within codes like TALYS, still strongly rely on experimental data to constrain free parameters. Accurate...

contributed 12+3

The Belle II experiment at the SuperKEKB electron–positron collider provides a high-luminosity environment uniquely suited for precision studies of hadron physics. Although primarily designed for flavor physics, Belle II offers powerful opportunities to address key questions in non-perturbative QCD that are of direct interest to nuclear physics.
In this talk, I will present recent Belle II...

41. Belle II Tracking and Optimisation of Hit Finding

contributed 12+3

Reliable track reconstruction is vital for the success of the Belle II experiment, especially as detector conditions evolve. The full tracking chain in the Belle II Analysis Software Framework combines Central Drift Chamber (CDC)-seeded and Silicon Vertex Detector (SVD)-seeded tracking stages, which are merged and cleaned to produce final tracks using a Combinatorial Kalman Filter (CKF). We...
