278. Nuclear-physics data for modeling of the r-process

Experiments in nuclear astrophysics

Invited

Nucleosynthesis theory predicts that about half of the chemical elements above iron are formed in explosive stellar scenarios by the r-process, i.e. a combination of rapid neutron captures, inverse photodisintegrations, and slower beta-decays, beta-delayed processes, as well as fission and possibly interactions with neutrinos. A correct modelling of this process, therefore,...

Experiments in nuclear astrophysics

Oral contribution

The complete understanding of the r-process still remains a challenge not only because of the identification of the possible astrophysical sites but also because of the interpretation of the observed abundances. With respect to this latter point, one of the main problems we have to overcome to fully understand the observed r-process abundances is the lack of information on the nuclei...

195. Building nuclei from the ground up

Nuclei far from stability

Oral contribution

Investigations of rare isotopes in the laboratory are opening the way to understand and clarify the properties of all nuclei and bulk nuclear matter. In this talk I will assess where we stand today in solving the nuclear problem and how future rare isotope facilities will impact our understanding of nuclei and our ability to predict nuclear properties in stellar and other environments....

272. Mass measurements of exotic nuclei and their role in stellar nucleosynthesis

Nuclei far from stability

Invited

The mass of nuclides far from stability provides information on decay and reaction energies that is crucial for modeling stellar nucleosynthesis. Low production rates, short half-lives, and the inherent precision required make masses perhaps the most difficult nuclear quantity to measure. The minuteness of the binding energy has also contributed to confounding attempts at reliable...
