Exploration of neutron-rich isotopes around N = 50 via the in-flight fission of a 345 MeV/Nucleon 238U beam

A search for new neutron-rich isotopes beyond Z = 28 and N = 50 was performed using a 345 MeV/nucleon 238^U 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 firs...

Sumario:A search for new neutron-rich isotopes beyond Z = 28 and N = 50 was performed using a 345 MeV/nucleon 238^U 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 72^Cr, 74,75^Mn, 77^Fe, 79,80^Co, 85^Cu, and 90^Ga. This study broadens our understanding of nuclear existence and paves the way for investigating the properties of neutron-rich medium-mass nuclei.
