在橡树岭国家实验室的Holifield放射性离子束装置上，研究了~（75）Cu [t1/2 = 1.222（8）s]到~（75）Zn的衰变。在低能放射性离子束光谱站使用高分辨率等压线分离器收集和数据，以获得每秒超过2000个离子的纯化的75 Cu束。首次确定了~（75）Zn的激发态。共120射线转换放置在一个水平计划，包含59个级别，包括两个以上的中子分离能量和一个以前未知的1/2同质异能态在127千电子伏的状态。根据观察到的馈送和衰变模式，推导和解释了几个态的自旋和宇称。
The decay of 75Cu [t1/2 = 1.222(8) s] to levels in 75Zn was studied at the Holifield Radioactive Ion Beam Facility of Oak Ridge National Laboratory. The and data were collected at the Low-energy Radioactive Ion Beam Spectroscopy Station using the high-resolution isobar separator to obtain a purified 75Cu beam with a rate of over 2000 ions per second. The excited states in 75Zn have been identified for the first time. A total of 120 -ray transitions were placed in a level scheme containing 59 levels including two states above the neutron separation energy and a previously unknown 1/2 isomeric state at 127 keV. Spins and parities of several states were deduced and interpreted based on the observed feeding and -decay pattern.
