16. HI-TREX: Next Generation of Transfer-Reaction Experiments at HIE-ISOLDE

Kathrin Wimmer (University of Cologne)

21/08/2026, 10:40

HI-TREX is the next-generation silicon detector array for transfer-reaction studies at HIE-ISOLDE. Improved granularity, increased solid-angle coverage, modern ASIC-based readout electronics, and enhanced rate capability will significantly extend the experimental possibilities for charged-particle spectroscopy in combination with the MINIBALL $\gamma$-ray spectrometer.

12. OSCAR at ISOLDE

Dr Vetle Wegner Ingeberg (Department of Physics, University of Oslo)

For the next run period at ISOLDE, the Nuclear Physics group at the University of Oslo are considering proposing a longer experimental campaign with the Oslo SCintillator ARay (OSCAR). The main aims of such a campaign will be to measure the nuclear level density and $\gamma$-ray strength function of key nuclei relevant for nuclear structure and nuclear astrophysics (e.g. i-process...

23. Post-accelerated polarized radioactive ion beams? Why and possibly how.

Georgi Georgiev (Université Paris-Saclay (FR))

Getting control of an additional degree of freedom of a system is a dream and a challenge for any experimentalist. Experiments with spin-polarized stable beams were done around 1990’s. However, with the change of the paradigm and the advances of Radioactive Ion Beam (RIB) - based nuclear structure studies, this subject of research has been slowly fading away. The questions that we would like...

15. Synergy betwen HIE-ISOLDE and LIC Studies of Nuclear Shapes

Jose Nicolas Orce Gonzalez (University of the Western Cape (ZA))

21/08/2026, 13:30

Here we present the scientific motivation for investigating the shapes of benchmark nuclei at the LHC ($^{12}$C, $^{24}$Mg, $^{48}$Ca, $^{76}$Ge-$^{86}$Kr and $^{136}$Xe-$^{136}$Ba), which can also be studied through low-energy Coulomb-excitation measurements at HIE-ISOLDE. By combining complementary measurements across these two energy regimes, these benchmark nuclei offer a unique...

35. Probing exotic nuclei with an active target in a magnetic field: the AT-TPC at ISS

Yassid Ayyad (Universidade de Santiago de Compostela)

Direct reactions in inverse kinematics are among the most powerful probes of the structure of exotic nuclei, but their study with post-accelerated radioactive beams is often limited by the trade-off between target thickness and resolution, and by the low intensities available for the most exotic species. We propose to bring the Active Target Time Projection Chamber (AT-TPC) to ISOLDE and to...
