RIKEN Nishina Center RI Beam Factory 使用 345 MeV/核子 238U 束流在富中子稀土区域寻找新同位素。使用 BigRIPS 飞行分离器对产生的碎片进行分析和鉴定。我们总共观测到了29种新的富中子同位素：153Ba、154,155,156La、156,157,158Ce、156,157,158,159,160,161Pr、162,163Nd、164,165Pm、166,167Sm、 169Eu、171Gd、173,174Tb、175,176Dy、177,178Ho 和 179,180Er。
A search for new isotopes in the neutron-rich rare-earth region has been carried out using a 345 MeV/nucleon 238U beam at the RIKEN Nishina Center RI Beam Factory. Fragments produced were analyzed and identified using the BigRIPS in-flight separator. We observed a total of 29 new neutron-rich isotopes: 153Ba, 154,155,156La, 156,157,158Ce, 156,157,158,159,160,161Pr, 162,163Nd, 164,165Pm, 166,167Sm, 169Eu, 171Gd, 173,174Tb, 175,176Dy, 177,178Ho, and 179,180Er.
