论文摘要
我们对所有稳定的Yb $^+$ ion的均匀同位素进行了田间同位素移位的原子相对论多体计算。我们证明，如果我们从一系列状态的核模型中采用YB同位素的核参数，这些核模型都预测了强烈的四极核核变形，然后计算出的国王图的非线性，这是由不同同位素的变形引起的，则与实验中的非线性相一致（Ilian counts counts al em et al em em em et and and a em et and and em em et and and em em et and em em et and em em et and。 125}，123002（2020））。从实验中提取的同位素之间的核RMS半径的变化与核计算中获得的变化是一致的。
We perform atomic relativistic many-body calculations of the field isotope shifts and calculations of corresponding nuclear parameters for all stable even-even isotopes of Yb$^+$ ion. We demonstrate that if we take nuclear parameters of the Yb isotopes from a range of the state-the-art nuclear models which all predict strong quadrupole nuclear deformation, then calculated non-linearity of the King plot, caused by the difference in the deformation in different isotopes, is consistent with the non-linearity observed in the experiment (Ian Counts {\em et al}, Phys. Rev. Lett. {\bf 125}, 123002 (2020)). The changes of nuclear RMS radius between isotopes extracted from experiment are consistent with those obtained in the nuclear calculations.
