摘要

我们报告了直接测量$7s\ ^2S_{1/2}\右划$ $7p\ ^2P_{3/2}$在$^{226}$Ra$^{+}$中的电偶极子跃迁频率。以激光冷却的镭离子为例，用倍频光直接驱动跃迁，并以碘为参考测量非倍频光的频率，确定跃迁频率为785722.11(3)GHz。该测量解决了先前报告值之间的五个联合标准偏差的差异。

Direct measurement of the 7s2S1/2→7p2P3/2 transition frequency in Ra+226

We report a direct measurement of the $7s\ ^2S_{1/2}\rightarrow$ $7p\ ^2P_{3/2}$ electric-dipole transition frequency in $^{226}$Ra$^{+}$. With a single laser-cooled radium ion we determine the transition frequency to be 785722.11(3) GHz by directly driving the transition with frequency doubled light and measuring the frequency of the un-doubled light with an iodine reference. This measurement addresses a discrepancy of five combined standard deviations between previously reported values.
