Invited speakers

The solenoidal-spectrometer technique was pioneered at Argonne just over 15 years ago with the HELIOS spectrometer. Its success has been emulated in Europe at CERN’s HIE-ISOLDE facility with the ISOLDE Solenoidal Spectrometer and at DOE’s Facility for Rare Isotope Beams with SOLARIS. Solenoidal spectrometers are highly versatile tools, perhaps more so than originally imagined, for studying...

61. Abrupt structural transition in exotic molybdenum isotopes unveils an isospin-symmetric island of inversion

Contributed Talks

Protons and neutrons in nuclei are arranged in orbitals that follow a shell structure, with energy gaps at specific magic numbers. Experiments using radioactive beams have shown that these magic numbers vanish in some neutron-rich isotopes. This results in unusual arrangements, where configurations with nucleons scattered to higher energy orbitals are the most bound, forming what has been...

123. Direct Observation of Superallowed Alpha Decay of 104Te

Ian Cox (Argonne National Laboratory)

Contributed Talks

Historically, the simplest $\alpha$ decay is that of $^{212}$Po, which is conceptualized as a doubly magic $^{208}$Pb core with a valence $\alpha$ particle. For decades, this well-measured isotope has stood as the baseline for $\alpha$-decay models and comparison among other $\alpha$-emitting nuclei. However, a lighter region of $\alpha$ radioactivity was found in neutron-deficient tellurium...

66. Fast-Beam One-Neutron Pickup Reactions: A Selective Probe of High-ℓ States

Thomas Parry (Facility for Rare Isotope Beams)

2026-07-28, 3:10 p.m.

Contributed Talks

High-$\ell$ single-particle configurations provide critical information on nuclear structure and place important constraints on theoretical models but are typically difficult to access experimentally due to their weak population in commonly used experimental methods such as low-energy transfer and knockout reactions. Intermediate-energy one-neutron pickup reactions in inverse kinematics are...
