我们利用柱形彭宁陷阱中的单离子，测定了类氢⁸-Si-⁺中电子束缚的g因子的实验值。根据离子的回旋频率与诱导自旋翻转频率的比值，得到g=1.995 348 958 7(5)(3)(8)。它与1.995 348 958 0(17)的最新理论值非常一致，该值包含了高达(Zα)2和(Zα)⁴)量级的双回路量子电动力学贡献，并代表了对束缚态量子电动力学计算的严格测试。
We determined the experimental value of the g factor of the electron bound in hydrogenlike ²⁸Si¹³⁺ by using a single ion confined in a cylindrical Penning trap. From the ratio of the ion's cyclotron frequency and the induced spin flip frequency, we obtain g = 1.995 348 958 7(5)(3)(8). It is in excellent agreement with the state-of-the-art theoretical value of 1.995 348 958 0(17), which includes QED contributions up to the two-loop level of the order of (Zα)² and (Zα)⁴ and represents a stringent test of bound-state quantum electrodynamics calculations.
