标题： Isotope Shifts of the $6d\,^2$D$_{3/2}\,$ - $7p\,^2$P$_{1/2}\,$ Transition in Trapped Short-Lived $^{209-214}$Ra$^+$

摘要： 激光光谱学研究在直线Paul阱中进行的短寿命镭同位素。 测量了 $6d\,^2$D$_{3/2}\,$ - $7p\,^2$P$_{1/2}\,$ 转换在 $^{209-214}$Ra$^+$ 中的同位素位移，这些位移对原子波函数的短程部分敏感。 这些结果是提高原子结构计算精度的重要实验输入。 这对于在Ra$^+$ 中研究宇称不守恒以确定弱混合角是必不可少的。 显示英文摘要

摘要： Laser spectroscopy of short-lived radium isotopes in a linear Paul trap has been performed. The isotope shifts of the $6d\,^2$D$_{3/2}\,$ - $7p\,^2$P$_{1/2}\,$ transition in $^{209-214}$Ra$^+$ were measured, which are sensitive to the short range part of the atomic wavefunctions. The results are essential experimental input for improving the precision of atomic structure calculation. This is indispensable for parity violation in Ra$^+$ aiming at the determination of the weak mixing angle.
