5. Study of oxygen isotopes at neutron-rich extreme

Yosuke Kondo (Tokyo Institute of Technology)

7/22/24, 10:50 AM

One of the goals of nuclear physics is to understand the properties of
all of the atomic nuclei including ones with large proton-neutron
asymmetry. The nuclear shell structure is a key to understanding the
strongly-interacting many-nucleon system and the doubly magic nucleus is
a cornerstone for that. The shell structure and magic numbers are well
established from the studies of...

6. Probing Nuclear Structure of the Edge of the N=20 Region of Deformation through the β-decay of Exotic Ne and Na Isotopes

Yiyi Zhu (UMass Lowell)

Neutron-rich nuclei in the N=20 region of deformation have played a key role in our understanding of nuclear structure. In this mass region, so-called intruder states from nucleon occupations in the pf-shell are observed to energetically compete with the expected configurations in the sd-shell. Although nuclei in this mass region can be experimentally challenging to access, β-decay can clearly...

7. Isomer Discoveries at FRIB with the FDSi Near N=20, 28, and 40

Mitch Allmond (Oak Ridge National Laboratory)

7/22/24, 11:35 AM

The Facility for Rare Isotope Beams (FRIB) will provide unprecedented access to exotic nuclei; approximately 80% of the isotopes predicted to exist up to uranium (Z = 92) will be produced. The FRIB Decay Station initiator (FDSi), led by the FDSi Coordination Committee and supported by the FDSi Group and Working Groups, is the initial stage of the FRIB Decay Station (FDS).
A brief overview of...

8. Revealing the nature of near-threshold narrow resonances in 11B with the HELIOS spectrometer

Yassid Ayyad (Instituto Galego de Fısica de Altas Enerxias, University of Santiago de Compostela)

7/22/24, 11:55 AM

The large branching ratio observed in the β-delayed proton emission of 11Be was explained by the existence of a narrow, near-threshold proton-emitting resonance in 11B. The direct measurement of this process sparked a heated debate surrounding the properties of this resonance and the unusually large β-decay branching ratio that populates it. Since then, several experiments have reported the...
