Fragmentation cross-sections of 1 GeV/u 208Pb on 9Be measured at the FRS — •Suraj K. Singh for the S450 collaboration — GSI, Darmstadt, Germany — Justus-Liebig-Universität Gießen, Germany
Studies of nuclei far from the valley of stability, where extreme proton-to-neutron ratios appear, are particularly interesting because they provide insight into the nuclear structure and astrophysical nucleosynthesis processes. The nuclei are important for studies of the nuclear-existence limit, and for the understanding of nuclear reaction mechanisms. For such studies of the exotic isotopes, production cross-section measurements are the basic step of any research. The knowledge of accurate production cross-sections is essential for further development of reaction models and every new experiment based on a certain reaction. In this contribution, the evaluation of production cross-sections of exotic nuclei close to N=126, produced in fragmentation of a 1 GeV/u 208Pb beam on a 9Be target and separated in-flight at fragment separator FRS at GSI will be presented.
