Unambiguous identification and investigation of uranium projectile fragments & discovery of 63 new neutron-rich isotopes in the element range 61 less-than or equal to Z less-than or equal to 78 at the FRS
The research of exotic, short-lived nuclei is a main contribution of modern nuclear physics to improve the knowledge of the strong interaction and to understand the synthesis of elements in stellar media. Nature is still ahead of the laboratories since in the astrophysical r-process very neutron-rich nuclides are continuously created which we just barely reach or which still have to be discovered. For this challenge new powerful accelerators and experimental tools have been developed to expand the frontiers of discovered nuclides. Besides a high intensity primary beam efficient and very sensitive in-flight separators are needed to access new nuclides in this field. To exploit the full discovery potential also the applied particle detectors and especially the unambiguous identification have to be steadily improved and extended in the experiments. In the presented work Uranium projectile fragmentation and fission have been used to discover new neutron-rich nuclides in the Z-range above 60 at the FRS. In this region of heavy nuclides most radioactive beam facilities have clearly strong limitations.
