Invited Speaker / Conférencier(ère) invité(e)

TRIUMF’s Ion Trap for Atomic and Nuclear science (TITAN) is located at the Isotope Separator and Accelerator (ISAC) facility, Vancouver. Titan is a multiple ion trap system capable of performing high-precision mass measurements and in-trap decay spectroscopy. In particular TITAN has specialised in fast Penning trap mass spectrometry of short-lived exotic nuclei using its Measurement Penning...

Shape coexistence is associated with nuclear deformations at low excitation energies and has been a topic of extensive research in nuclear physics over the past 60 years. Shape coexistence is driven by two opposing forces. One is the stabilizing effect of closed shells causing the nucleus to have a spherical shape, while the other is the residual interaction between proton and neutrons, the...

2036. Decay Spectroscopy of Neutron-Rich Cd Around the N = 82 Shell Closure (G)*

The neutron-rich Cadmium isotopes around the well-known magic numbers at $Z=50$ and $N=82$ are prime candidates to study the evolving shell structure observed in exotic nuclei. Additionally, the extra binding energy observed around the nearby doubly-magic $^{132}$Sn has direct correlations in astrophysical models, leading to the second r-process abundance peak at $A\approx130$ and the...

2160. High-Precision Half-Life Measurement for the Superallowed $\beta^+$ Emitter $^{22}$Mg (G)*

Nuclear Physics / Physique nucléaire (DNP-DPN)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

High precision measurements of the $\mathcal{F}t$ values for superallowed Fermi beta transitions between $J^\pi = 0^+$ and isospin $T=1$ isobaric analogue states allow for stringent tests of the electroweak interaction described by the Standard Model. These transitions provide an experimental probe of the Conserved-Vector-Current hypothesis, the most precise determination of the up-down...

1957. Determination of proton radii of neutron rich oxygen isotopes from charge-changing cross section measurements. (G)*

Nuclear Physics / Physique nucléaire (DNP-DPN)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Charge radius is an important bulk property of the nucleus for investigating nuclear structure. The nuclei lying close to the boundaries of the nuclear chart (the drip lines) have revealed new features like halo and skin. Another new phenomenon that has emerged in the neutron-rich region is the changing or vanishing of magic numbers [1,2]. The knowledge of proton radii is crucial for...
