| Povzetek: | Neutron-rich isotopes far from stability were produced and observed at the projectile Fragment Separator (FRS) of the GSI Helmholtzzentrum für Schwerionenforschung in the FAIR Phase-0 experimental program. The isotopes were produced in April 2020 in the fragmentation of a 1.05 GeV/nucleon 208Pb beam on a beryllium target. The experiment targeted the neutron-rich region near the � = 126 shell closure, a key area for understanding the astrophysical r-process, but largely unexplored due to the experimental challenges in producing such exotic nuclei. Within this work, we identified five isotopes which were not seen previously at FRS; 184Tm, 195Ta, 198W, 200Re, and 201Re — the latter located directly on the � = 126 line. These observations corroborate the extension of the nuclear chart and highlight the capabilities of the FRS and of in-flight fragmentation at relativistic energies in accessing this region. |
