使用 ISOLDE-CERN 的彭宁阱质谱仪 ISOLTRAP 对缺中子同位素中的低自旋态和高自旋态进行直接质量测量。这些测量允许确定由轨道引起的异构态的激发能。此外，该区域中的铅、氡和镭同位素的异构态的激发能是从衰变链获得的。这些激发能量完善了该区域的能量系统学知识，并证实了状态保持同分异构，与价中子的数量无关。
Direct mass measurements of the low-spinand high-spinstates in the neutron-deficient isotopesandwere performed with the Penning-trap mass spectrometer ISOLTRAP at ISOLDE-CERN. These measurements allow the determination of the excitation energy of the isomeric state arising from theorbital in. Additionally, the excitation energy of isomeric states of lead, radon, and radium isotopes in this region were obtained from-decay chains. These excitation energies complete the knowledge of the energy systematics in the region and confirm that thestates remain isomeric, independent of the number of valence neutrons.
