利用共振电离激光离子源和欧洲核子研究中心（CERN）的风车探测装置，对缺中子同位素进行了激光电离和质量分离研究。新的和改进的数据复杂的fine-structuredecay的三种同位素推导，提供洞察的低水平的子核。还获得了衰变子产物性质的新信息。从第一次在源激光光谱测量的原子267.6 nm跃迁的超精细结构，推导出高和低自旋衰变状态的核磁矩。与从加和关系确定的值一起，它们被用来提出两个状态的最可能的自旋和配置。衰变分支比测定为和。
A study of the laser-ionized and mass-separated neutron-deficient isotopeswas performed using the Resonance Ionization Laser Ion Source and the Windmill detection setup at ISOLDE, CERN. New and improved data on complex fine-structuredecays of the three isotopes were deduced, providing insight into the low-lying levels in the daughter nuclei. New information on the properties of-decay daughter productswas also obtained. From the first in-source laser spectroscopy measurements of the hyperfine structure in the atomic 267.6-nm transition of, the nuclear magnetic moments for both high- and low-spin-decaying states were deduced. Together with the values determined from the additivity relations, they were used to propose the most probable spins and configurations for both states. The-decay branching ratios were determined asand.
