在Legnaro国家实验室，用460 MeV 70Zn束流轰击238U靶，通过多核子转移研究了N = 34 ~ 40的富中子Co同位素。用高接受度磁谱仪（PRISMA）鉴定离子，用一组HPGe三叶草探测器（CLARA）检测伽马辐射，记录了伽玛反冲巧合。并与大尺度壳模型计算结果进行了比较。
Neutron-rich Co isotopes from N = 34 to 40 were studied through multinucleon transfer by bombarding a 238U target with a 460 MeV 70Zn beam at the Legnaro National Laboratories. Gamma-recoil coincidences were recorded identifying the ions by using a high-acceptance magnetic spectrometer (PRISMA) and detecting the gamma radiation by using an array of HPGe clover detectors (CLARA). The results are discussed in comparison with the predictions of large-scale shell-model calculations.
