Abstract |
A search for new neutron-rich isotopes beyond Z=28 and N=50 was performed using a 345 MeV/nucleon 238U beam at RI Beam Factory in RIKEN Nishina Center. The BigRIPS separator and state-of-the-art radiation detectors were used to efficiently separate and identify the produced nuclei. For the first time, we have observed and determined the production cross sections for eight neutron-rich isotopes 72Cr, 74,75Mn, 77Fe, 79,80Co, 85Cu, and 90Ga. This study broadens our understanding of nuclear existence and paves the way for investigating the properties of neutron-rich medium-mass nuclei. |
