论文摘要
我们报告了$ 7S \ ^2S_ {1/2} \ rightArrow $ $ 7p \ ^2p_ {3/2} $电动偶极转换频率$ ^{226} $ ra $ ^{+} $中的直接测量。使用单个激光冷却的镭离子，我们通过以频率加倍的光直接驱动过渡，并通过碘参考来测量未加倍的光的频率，从而确定过渡频率为785722.11（3）GHz。该测量解决了先前报道的值之间五个综合标准偏差的差异。
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 undoubled light with an iodine reference. This measurement addresses a discrepancy of five combined standard deviations between previously reported values.
