论文摘要
我们报告了两种过渡的同位素变化的测量值（$ 4F^46S \ rightarrow [25044.7]^{\ circ} _ {7/2} $和$ 4F^46S \ rightArrow [25138.6]精度，使用低温冷却中性血浆的激光光谱法。在跨越核形状跃迁的五个旋转零同位素上测量了同位素移位。我们讨论了使用光学时钟过渡的ND $^+同位素转移准确性的进一步改进的前景，这可以实现对新物理搜索的国王情节线性的更高精度测试。
We report measurements of the isotope shifts of two transitions ($4f^46s\rightarrow [25044.7]^{\circ}_{7/2}$ and $4f^46s\rightarrow [25138.6]^{\circ}_{7/2}$) in neodymium ions (Nd$^+$) with hundredfold improved accuracy, using laser spectroscopy of a cryogenically-cooled neutral plasma. The isotope shifts were measured across a set of five spin-zero isotopes that spans a nuclear shape transition. We discuss the prospects for further improvements to the accuracy of Nd$^+$ isotope shifts using optical clock transitions, which could enable higher precision tests of King plot linearity for new physics searches.
