  1. 257. Isoscalar electric giant resonances: Compression modes and nuclear incompressibility

    Invited Presentation

    A rich spectrum of giant resonances of different multipolarities and spin and isospin structure was expected on theoretical grounds. In the nineteen seventies, the isoscalar giant quadrupole resonance (ISGQR) was discovered in electron scattering followed by the isoscalar giant monopole resonance (ISGMR) in inelastic $\alpha$ scattering. In the last five decades, the compression modes the...

  2. 409. The Scissors Mode: A Building Block of Low-Energy Nuclear Structure
    Peter von Neumann-Cosel (Institut für Kernphysik, TU Darmstadt)

    Nuclear Structure, Spectroscopy and Dynamics
    Invited Presentation

    The magnetic dipole scissors mode and its implications for the low-energy structure of heavy nuclei are discussed. Salient features like its orbital nature, the correlation of the strength with ground-state deformation, the collectivity and a systematic description within a sum-rule approach are reviewed [1]. The scissors mode is also observed in the quasicontinuum and may be related to the...

  3. 159. Search for 22Na in novae supported by a novel method for measuring femtosecond nuclear lifetimes.

    Invited Presentation

    Simulations of explosive nucleosynthesis in novae predict the production of the radioisotope 22Na. Its half-life of 2.6 yr makes it a very interesting astronomical observable by allowing space and time correlations with the astrophysical object. Its 𝛾-ray line at 1.275 MeV has not been observed yet by 𝛾-ray space observatories. This radioisotope should bring constraints on nova models and help...

  4. 173. Theory of nuclear matter: ab initio developments and connections to the nuclear energy functional

    Invited Presentation

    Infinite nuclear matter lies at the crossroads of nuclear physics investigations, as it connects the microscale of nuclei and the macroscale of compact celestial bodies. On the one hand, nuclear matter properties can be partially constrained by finite nuclei observables and astrophysical observations. On the other hand, nuclear matter can guide the development of both ab initio nuclear...

  5. 356. Observation of the radiative decay of the low energy thorium-229 isomer: En route towards a nuclear clock
    Mr Sandro Kraemer (Instituut voor Kern- en Stralingsfysica, KU Leuven)

    Nuclear Structure, Spectroscopy and Dynamics
    Invited Presentation

    The radioisotope thorium-229 features a nuclear isomer with an exceptionally low excitation energy of ≈ 8.4 eV and a favorable coupling to the environment, making it a candidate for a next generation of optical clocks allowing to study fundamental physics such as the variation of the fine structure constant [1,2].
    While first indirect experimental evidence for the existence of such a nuclear...
