论文摘要
在离子导板质谱仪的Jyfltrap Penning Trap质谱仪上，在离子指南同位素分离器在线（Igisol）设施的Jyfltrap Penning TRAP质谱仪进行了精确的质量测量。我们报告了$^{110,112,114,116,118} $ RH的地面和异构体状态质量的结果，以及$^{120} $ RH的第一个质量测量。使用相似离子 - 环体共振（PI-ICR）技术将异构态分开并首次测量。对于$^{112} $ RH，我们还报告了基态和异构体的新半衰期。将结果与使用BSKG1质量模型的理论预测进行了比较，并根据三轴变形进行了讨论。
Precision mass measurements of neutron-rich rhodium isotopes have been performed at the JYFLTRAP Penning trap mass spectrometer at the Ion Guide Isotope Separator On-Line (IGISOL) facility. We report results on ground- and isomeric-state masses in $^{110,112,114,116,118}$Rh and the very first mass measurement of $^{120}$Rh. The isomeric states were separated and measured for the first time using the phase-imaging ion-cyclotron-resonance (PI-ICR) technique. For $^{112}$Rh, we also report new half-lives for both the ground state and the isomer. The results are compared to theoretical predictions using the BSkG1 mass model and discussed in terms of triaxial deformation.
