Projectile fragmentation cross-sections of 1 GeV/u 208Pb on 9Be measured at the FRS — •Suraj Kumar Singh for the S450 collaboration — GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany — Justus-Liebig-Universität Gießen, Germany
Studies of nuclei far from the valley of stability are of interest because they provide insight into nuclear reactions and nuclear structure relevant for various fields of physics ranging from fundamental physics, nuclear astrophysics up to applications in medicine. Therefore, it is important to produce and study such exotic nuclides at the edges of stability to get an inside of their sometimes new or unexpected properties. The rate and yield estimates for studies of the exotic isotopes are based on their production cross-sections. As calculations are difficult, production cross-section measurements are the first step towards research with isotopes far away from the valley of stability and the knowledge of accurate production cross-sections is essential for each proposal for new experiments. In this contribution, the evaluation and first results of production cross-sections of exotic nuclei in the vicinity of isotones with “magic number” 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.
