  5. 69. Direct Measurements of (α,n) Reactions for Nuclear Astrophysics with ARIEL
    Dr Matthew Williams (Univesisity of Surrey)
    2026-04-20, 1:50 p.m.

    Reactions induced by alpha-particles that result in the emission of neutrons play a critical role across multiple disciplines of fundamental and applied nuclear physics. However, essential cross-section data for many key (α,n) reactions are either discrepant or entirely unmeasured. In nuclear astrophysics, this deficiency severely impacts models that describe how heavy elements are formed...

    microscopic structure of atomic nuclei. In particular, they are
    sensitive to single-particle occupancies and wave-function overlaps,
    offering direct insight into the interplay between single-particle and
    collective degrees of freedom. This makes them ideally suited to
    investigate shape coexistence in nuclei.
    In this...

    Aiko Takamine (Institute of Science Tokyo)
    2026-04-22, 1:30 p.m.

    Radium isotopes near $A=$220-230 exhibit strong octupole correlations, evidenced by low-lying negative-parity states and enhanced E3 transition strengths in even-even nuclei [1,2]. However, whether the underlying octupole deformation is static (a genuine ground-state symmetry breaking) or dynamic (a collective shape vibration) remains an open question.

    In this contribution, the possibility...

  80. 59. Opportunities for direct measurements of weak r-process reactions with ARIEL beams
    Ben Reed (TRIUMF/Saint Mary's University)
    Contributed poster presentation
    Reception & Poster Session

    Work has already been done at TRIUMF to directly study ($\alpha$,n) reactions using both DRAGON and EMMA, with the aid of the DEMAND neutron detector array. These reactions are important for understanding both the weak r-process and the s-process. Many of the reactions relevant to the weak r-process involve neutron-rich radioactive nuclei. ARIEL will expand TRIUMF’s rare isotope beam...

  81. 22. Physics Opportunities with TRIUMF's neutral atom trap for beta decay (TRINAT)
    John Behr (TRIUMF)
    Contributed poster presentation
    Reception & Poster Session

    TRINAT has at least four existing efforts with opportunities for collaborators and their students. A correlation between spin, beta, and recoil has enhanced sensitivity to time-reversal odd, parity-even, isospin-breaking nucleon-nucleon interactions because of 47K decay's isospin-hindered Fermi component, making it potentially complementary to MORA's more general decays as well as to electric...

  101. 67. The Missing Nuclear and Atomic Spectroscopy Enabled in the ARIEL Era via the TITAN-EBIT
    John Ash (TRIUMF), Masoumeh Dehghan (TRIUMF)
    Contributed poster presentation
    Reception & Poster Session

    Experiments of highly suppressed or forbidden nuclear decays, like double-gamma decay or nuclear excitation by electron capture, require weeks-long setup and observation times in the TITAN-EBIT, which had been curtailed by the over-subscription of the ISAC era. The results of these experiments have far-reaching implications, including direct probes of electric dipole polarizability and the...

  102. 31. The neighborhood of $^{78}$Ni: Probing the N = 50 Shell Closure with ARIEL Photofission
    Pavithra Weligampola (TRIUMF), Alec Cannon (University of Victoria)
    Contributed poster presentation
    Reception & Poster Session

    The neutron-rich region surrounding $^{78}$Ni provides a stringent test of nuclear structure far from stability and plays a central role in the astrophysical r-process responsible for the A≈80 abundance peak. As a doubly-magic nucleus, $^{78}$Ni offers a key benchmark for investigating the persistence of the N = 50 shell closure in extremely neutron-rich nuclei. However, direct mass...

  103. 11. The Refined Bohr-Mottelson Model for the Description of Collective Motion in Atomic Nuclei
    Helena Lo (Simon Fraser University)
    Contributed poster presentation
    Reception & Poster Session

    The development of ARIEL and other new facilities which expand experimental capabilities to study atomic nuclei triggers the need to advance theories of nuclear structure and reactions. A strong theoretical framework addressing nuclear properties from first-principles is necessary to direct exploration, formulate informative experiments, and interpret the data that ARIEL will grant access...

  104. 29. Timepix3-Based Optical Time Projection Chamber: Fast 3D Tracking for Low-Energy Nuclear Experiments
    Cristina Cabo Landeira (IGFAE - Universidade de Santiago de Compostela)
    Contributed poster presentation
    Reception & Poster Session

    An optical Time Projection Chamber (oTPC) is proposed for low-energy nuclear physics experiments at TRIUMF/ARIEL, using a Timepix3-based single-photon camera as readout. When charged particles ionize the detector gas, the resulting electron avalanches produce scintillation light captured by an externally mounted camera with an image intensifier — avoiding the complexity of conventional...

    Safiia Ismagilova
    Contributed poster presentation
    Reception & Poster Session

    Nuclear reactions reveal critical information about nuclear structure and nuclear astrophysics. Some studies, like half-life determinations, are directly relevant to understanding the evolution of nuclear shells, while others have an indirect impact through the production of exotic species to advance the pathway of the rapid-neutron-capture process. The common requirement for these studies at...

  106. 76. Using Solar r-process abundances to probe nuclear masses with Markov Chain Monte Carlo
    Aiden Magor
    Contributed poster presentation
    Reception & Poster Session

    R-process nucleosynthesis is an important astrophysical process that is responsible for generating many of the heavy elements that we see in stars and in our own Solar System today. The exact events that occurred which enriched our Solar System with heavy elements is still a mystery. For example, the origin of the rare earth peak at A ~ 164 that arises in between the second and third peak from...
