EMMI workshop: Neutron Matter in Astrophysics: From Neutron Stars to the r-Process

The abundances of r-process nucleosynthesis in the mass A=130 region are largely affected by the nuclear structure properties around the N=82 magic number. Some simulations show a better description of the abundances if a shell quenching of N=82 is assumed. In addition, the anomalous behavior of the experimental 2+ excitation energies in neutron rich Cd isotopes has been interpreted as an...

Within the Generalized Energy-density Functional method we have systematically calculated the beta-decay total energy releases, half-lives and beta-delayed neutron emission branchings for near-spherical nuclei with charge numbers Z = 60 - 80 near the neutron shell at N = 126. Together with our previous calculations this provides a basic set of the weak rates for the r-process modeling. Our...

Radiation Pressure Acceleration (RPA) with solid state density ion bunches, which are about 1E15 times more dense then classically accelerated ion bunches, allow for a high probability that generated fission products fuse again, when the thorium beam strikes a second close Th target. The fission fragments have a 1/sin(Theta) angular distribution and thus are predominantly emitted in beam...
