Opportunities for a better understanding of the synthesis of the heavy elements at the National Ignition Facility, Lawrence Livermore National Lab — Kathrin Göbel1, Tanja Heftrich1, Alisa Lier1, •René Reifarth1, Kerstin Sonnabend1, Joseph A.

The elements beyond iron are produced by neutron captures in the s and the r processes, by proton captures or via photodisintegration reactions.
The National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory, CA, USA, offers unique, unprecedented opportunities to investigate some of the important reactions in a completely complementary approach. The high densities and temperatures in the plasma allow the investigation under almost stellar conditions. The experimental challenge is, however, the extreme short time during which such conditions are available.
Some ideas and options for experiments with astrophysical motivation at NIF will be discussed. Currently sensitivity studies for upcoming experiments are carried out. First results will be presented.
This project was supported by the Helmholtz International Center for FAIR, the Helmholtz Young Investigator Group VH-NG-327, DFG (SO907/1-2) and HGS-HIRe.
