论文摘要
高分辨率离子（HCI）的冷却，捕获和量子逻辑光谱方面的最新实验进展使得HCIS可用于高分辨率光谱和精确基础研究。基于这些成就，我们探索了使用地面和低较低激发态在CF $^{15+} $和CF $^{17+} $ ions中的低洼兴奋状态之间开发光学时钟的可能性。使用高准确的相对论计算方法，我们预测了时钟过渡的波长，计算了相关的原子特性，并分析了影响精度和稳定性的精确度和稳定性的许多系统效应（例如电动四极，微动 - 和Quadratic Zeeman的时钟转变）。我们还计算了时钟状态的磁性偶极性超精细结构常数和时钟过渡的黑体辐射移位。
Recent experimental progress in cooling, trapping, and quantum logic spectroscopy of highly-charged ions (HCIs) made HCIs accessible for high resolution spectroscopy and precision fundamental studies. Based on these achievements, we explore a possibility to develop optical clocks using transitions between the ground and a low-lying excited state in the Cf$^{15+}$ and Cf$^{17+}$ ions. Using a high-accuracy relativistic method of calculation we predicted the wavelengths of clock transitions, calculated relevant atomic properties, and analyzed a number of systematic effects (such as the electric quadrupole-, micromotion-, and quadratic Zeeman shifts of the clock transitions) that affect the accuracy and stability of the optical clocks. We also calculated magnetic dipole hyperfine-structure constants of the clock states and the blackbody radiation shifts of the clock transitions.
