Production of hypernuclei in relativistic ion collisions.

• Alexander Botvina (FIAS, University of Frankfurt am Main)

Room: 414 The study of hypernuclei produced in relativistic collisions of heavy ions opens new opportunities for nuclear/particle physics and astrophysics. We review the main processes leading to the formation of hypernuclei in these reactions: These are the disintegration of large excited hyper-residues (target- and projectile-like remnants with captured hyperons), and the coalescence of hyperons with other baryons into light clusters. We use the transport, coalescence and statistical models to describe the whole process, and demonstrate the advantages over the traditional hypernuclear methods: A broad distribution of predicted hypernuclei in masses and isospin allows for investigating properties of exotic hypernuclei, as well as the hypermatter both at high and low temperatures. We point at the abundant production of multi-strange nuclei and new bound/unbound hypernuclear states. The realistic estimates of hypernuclei yields in various collisions are presented. Many processes well known in normal reactions, such as evaporation, fission, multifragmentation, and Fermi-break-up are generalized and calculated for the case of excited hypermatter. We demonstrate novel methods for analysis of hypernuclear data which allow for obtaining info on exotic hypernuclei. There is a saturation of the hypernuclei production at high energies, therefore, the optimal way to pursue this experimental research is to use the accelerator facilities of intermediate energies.

Radiation dominated implosion with plasmonic nano-shells and flat target

• Laszlo Csernai (Department of Physics and Technology)

Room: 414 Inertial Confinement Fusion is a promising option to provide massive, clean, and affordable energy for humanity in the future. The present status of research and development is hindered by hydrodynamic instabilities occur- ring at the intense compression of the target fuel by energetic laser beams. The initial compression of the target can be decreased, not to reach the Rayleigh-Taylor or other instabilities, and a final and more energetic laser pulse can achieve rapid volume ignition, which can be as short as the penetration time of the light across the pellet. The reflectivity of the target can be made negligible in the planned direct drive experiments, and the absorptivity can be increased by one or two orders of magnitude by plasmonic nano-shells embedded in the flat target fuel. Thus, higher ignition temperature and radiation dominated dynamics can be achieved. Here we propose that a short final light pulse can heat the target so that most of the interior will reach the ignition temperature simultaneously based on the results of relativistic fluid dynamics. This makes the development of any kind of instability impossible, which would prevent complete ignition of the target. In the new one-dimensional, two laser driven geometry, after the ignition the DT burn- ing will become faster and more intense than in the present LLNL NIF thermos-nuclear fusion experiments.
