  1. 145. Radioactive Nuclei from Recent Near-Earth Supernovae as Telltale Signatures for our Solar System History
    Jenny Feige

    Invited

    Within our solar neighbourhood (150-500 light years) tens of star explosions, i.e., supernovae, occurred within the last ~10 Myr. Their expanding shock fronts swept across our Solar System leaving traces of newly formed nucleosynthesis products on Earth, particularly long-lived radioactive nuclei such as $^{60}$Fe (t$_{1/2}$=2.6 Myr). I will present an overview on (1) accelerator mass...

  2. 112. Measurement of the 7Be(p,γ)8B reaction cross section at astrophysical energies with the recoil mass separator ERNA
    Raffaele Buompane (University of Campania and INFN-Naples)

    Oral

    The $\rm ^7Be(p,\gamma)^8B$ represents one of the more important reaction for the prediction of high energy component of solar neutrino spectrum. The importance of this reaction triggered an intense experimental work over the last decades, where discrepancies were observed between the results of different measurements.
    The origin of this discrepancy limit the overall precision and accuracy of...

  3. 154. Latest half-life measurements of Sm-146, Gd-148, and Dy-154 at Paul Scherrer Institute

    Oral

    Precise nuclear data is extremely important for several scientific applications, ranging from the calculation of reaction rates for the description of galactic events, to the evaluation of the toxicity of nuclear waste. As it was recently shown, the re-evaluated half-life data of a considerable number of radionuclides (e.g., Fe-60 [1], Se-79 [2, 3], and Sm-146 [4]) was in substantial...

  4. 64. Potential experimental evidence of an Efimov state in 12C and its influence on astrophysical carbon creation
    Giuseppe Cardella
    09/09/2022, 12:00
    Oral

    Recently we measured the gamma decay probability of 12C levels over the threshold for particle decay as the Hoyle and the 9.64 MeV levels [1] measuring for the first time the two gamma decay of such last level. We observe in our data a large gamma decay width, 3 times larger than the already larger than systematic result of Kibedi et al [2]. Investigating also on the 3-alpha decay channel of...

  5. 105. Proton capture on stored radioactive ions
    Sophia Florence Dellmann (Goethe University Frankfurt)
    09/09/2022, 12:15
    Oral

    By combining two unique facilities at GSI (Helmholtz Centre for Heavy Ion Research),
    the fragment separator (FRS) and the experimental storage ring (ESR), the first direct measurement of a proton capture reaction of a stored radioactive isotope has been accomplished. The combination of sharp ion energy, ultra-thin internal gas target, and the ability to adjust energy of the beam in the ring...
