  1. 152. Beta-decay along the N=Z line and its relevance in rp-process and X-Ray bursts
    Enrique Nacher (Univ. of Valencia and CSIC (ES))

    Invited

    Nucleosynthesis in Type I X-ray bursts (XRB) proceeds eventually through the rp-process near the proton drip-line. Several N=Z nuclei act as waiting points in the reaction network chain. Astrophysical calculations of XRB light curves depend upon the theoretical modelling of the beta decays of interest, with the N=Z and their second-neighbours N=Z+2 being key nuclei in this context.

  2. 124. Beta decay in Neutron Star Crusts

    Oral

    Low Mass X-ray Binaries that transiently accrete matter onto their neutron stars are excellent laboratories for studying dense matter physics. These systems go in and out of the quiescence phase over observational timescales of decades. Monitoring the surface temperatures of neutron stars in this phase reveals a great deal of information about their structure and composition. However, to infer...

  3. 78. Felsenkeller shallow-underground 5 MV accelerator
    Daniel Bemmerer
    07/09/2022, 09:45
    Oral

    For low-background cross-section measurements, it is beneficial to host an ion accelerator in an underground setting, shielded from cosmic rays. The Felsenkeller 5 MV underground ion accelerator in Dresden, Germany, is the second such facility in Europe and has recently become accessible using EU-supported transnational access. The contribution will review recent progress at Felsenkeller: The...

  4. 97. 57Zn β-delayed proton emission to constrain 56Ni rp-process waiting point
    Mansi Saxena
    07/09/2022, 10:00
    Oral

    Type-I X-rays bursts are thermonuclear flashes ignited on the surface of a neutron star which is accreting hydrogen and helium-rich material from its companion star. With an hours-long stellar half-life and a low proton capture Q value (~690 keV), doubly magic 56Ni has long been defined as one of the waiting points in the rapid proton capture (rp) process that powers the type-I X-ray bursts....

  5. 16. First measurement of a p-process reaction using a radioactive ion beam
    Dr Matthew Williams (TRIUMF)

    Oral

    Approximately 30 stable nuclides on the neutron-deficient side of stability cannot be produced via the same neutron-capture driven mechanisms responsible for synthesizing all other elements heavier than iron. These “p-nuclei” are instead thought to originate from photodisintegration reactions on s- and r-process seed nuclei, which can occur in the extreme high-temperature environments of...
