astrophysics/nucleosynthesis

invited presentation

Determining the stellar origin of the elements observed in our Galaxy today poses one of the key challenges in the field of nuclear astrophysics. Thus, we seek to understand the nuclear processes involved in stellar evolution, as their details give us insight into the fusion pathways and routes to the synthesis of heavy elements. The investigation of radiative capture reactions involving the...

334. From Tensor Currents to Solar Neutrinos: Precision Beta-Decay Studies of $^8$Li and $^8$B

spectroscopy

invited presentation

The $\beta$-decays of $^8$Li and $^8$B provide an important playground to search for physics beyond the Standard Model, and, additionally, a detailed study of $^8$B $\beta$-delayed $\alpha$-particles provides key insights needed to constrain the spectrum of high energy neutrinos emitted by the Sun. To accomplish both these aims, the $\beta$-decays of $^8$Li and $^8$B were studied with the...

442. Doubly magic 78Ni as a beta-delayed neutron precursor

oral contribution

78Ni is a unique doubly magic nucleus far from beta stability line, the only one decaying with β-delayed neutron emission channel. Its decay properties influence the early r-process nucleosynthesis and the beta decays of exotic nuclei north-east of Z=28 and N=50. Nuclei in the 78Ni region were created with the 345 MeV/u 238U beam reaching nearly 70 part*nanoAmp. Fragmentation products were...
