64. ACTAR TPC Studies of Direct and Resonant Reactions: Insights from the TRIUMF campaign

Beatriz Fernandez Dominguez (University of Santiago de Compostela)

2026-07-29, 11:00 a.m.

Invited speakers

The ACtive TARget and Time Projection Chamber (ACTAR TPC), is a versatile detector designed to address a wide range of nuclear physics topics near the drip-lines. In this contribution, previous results obtained with ACTAR TPC in transfer reaction studies with a 20O beam will be reviewed, demonstrating its capabilities for precise measurements in inverse kinematics. Particular emphasis will be...

70. Determination of the electromagnetic nature of the Low Energy Enhancement in the γ-ray strength function of 70Zn

Eleanor Ronning (INFN Padova)

2026-07-29, 11:30 a.m.

Contributed Talks

The γ-ray strength function ($\gamma$SF) is a statistical nuclear property that describes the likelihood of $\gamma$-ray emission as a function of $\gamma$-ray energy. Investigations into the $\gamma$SF have identified prominent features in its shape, such as the giant dipole resonance, pygmy dipole resonance, scissors mode, and low energy enhancement (LEE). The LEE is a fundamental property...

74. Charge Radii of 52,53Ni from Precision Laser Spectroscopy

Adam Dockery (Michigan State University / Facility for Rare Isotope Beams)

2026-07-29, 11:50 a.m.

Contributed Talks

The evolution of nuclear structure in the magic nickel chain provides stringent tests of nuclear theory with the presence of three doubly magic nuclei ($^{48,56,78}$Ni) and a prominent subshell closure at $^{64}$Ni. In this work, precision laser spectroscopy measurements on $^{52,53}$ Ni will be presented, which extend the known Ni charge-radii chain beyond doubly magic $^{56}$Ni towards the...

29. Support for multiple coexistence: the first lifetime measurements of the $0^+_3$ states in $^{118}$Sn and $^{120}$Sn

Frank (Tongan) Wu (Simon Fraser University)

2026-07-29, 12:10 p.m.

Contributed Talks

The semi-magic Sn nuclei, extending beyond the $N=50$ and $N=82$ shell closures, present one of the most-studied isotopic chains on the nuclear chart. $^{118}_{50}$Sn$_{68}$ and $^{120}_{50}$Sn$_{70}$ lie in the neutron mid-shell, where shape coexistence was proposed with the signature of deformed excited $0^+$ states intruding into the seniority-like spherical yrast bands. However, transition...
