  1. 150. New detection systems for an enhanced sensitivity in key stellar (n,γ) measurements
    Jorge Lerendegui Marco (Univ. of Valencia and CSIC (ES))

    Invited

    Neutron capture cross-section measurements are fundamental in the study of astrophysical phenomena, such as the slow neutron capture (s-) process of nucleosynthesis operating in red-giant and massive stars. One of the best suited methods to measure neutron capture (n,γ) cross sections over the full stellar range of interest is the time-of-flight (TOF) technique.

  2. 82. Measurement of the 140Ce(n,γ) cross section at n_TOF and astrophysical implications

    Oral

    Among the nucleosynthesis mechanism involving the heavy nuclei, the so-called slow (s-)process is one of the better known. Being responsible of about half of the element heavier than iron, many models were built in order to describe the process and the final element abundances.
    The s-process take place in the inner layers of AGB stars, where the heavy elements are produced during interpulses...

  3. 15. The study of the 20Ne(p,g)21Na reaction at LUNA

    Oral

    The NeNa and MgAl cycles are relevant to the synthesis of Ne, Na, and Mg isotopes: a detailed knowledge of the involved nuclear processes is fundamental to determine the nucleosynthesis during various stages of stellar evolution, in particular in the Red Giant Branch (RGB) and Asymptotic Giant Branch (AGB) phases, as well as in Novae explosions. Key reactions of these cycles are also thought...

  4. 137. A new approach to β-decays studies impacting nuclear physics and astrophysics: the PANDORA setup
    Domenico Santonocito
    08/09/2022, 12:00
    Oral

    Theory [1,2] predicts that lifetimes of beta-radionuclides can change dramatically as a function of their ionization state. Fully stripped ions in storage rings [3] have proven to change their lifetimes by several orders of magnitudes. The PANDORA (Plasmas for Astrophysics, Nuclear Decay Observation and Radiation for Archaeometry) [4,5] experiment is conceived to measure, for the first time,...

  5. 10. Measurement of the bound-state beta decay of Thallium-205 and its implications on the fate of Lead-205 in the early solar system
    Ragandeep Singh Sidhu (School of Physics and Astronomy, University of Edinburgh, EH9 3FD, UK)

    Oral

    Understanding the production and survival of $\mathrm{^{205}{Pb}}$ in stars is pivotal as $\mathrm{^{205}{Pb}}$ is the only short-lived radionuclide that is produced exclusively by the slow neutron capture process (s-process). The ratio of radioactive $\mathrm{^{205}{Pb}}$ to stable $\mathrm{^{204}{Pb}}$, when compared to the expected value from the continuous galactic nucleosynthesis, helps...
