类锂硅（28）Si（11+）的g因子已在三重penning阱中测量，相对不确定度1.1×10（-9）为g(exp)=2.000 889 889 9（21）。该值的理论预测值为g(th)=2.000 889 909(51)，由于首次对双光子交换校正进行了严格的评估，将精度提高到2.5×10（-8）。测量值与理论预测非常吻合，并对1s(2)2s态的g因子和磁场中相对论性多电子计算的束缚态QED进行了最严格的检验。
The g factor of lithiumlike silicon (28)Si(11+) has been measured in a triple-Penning trap with a relative uncertainty of 1.1×10(-9) to be g(exp)=2.000 889 889 9(21). The theoretical prediction for this value was calculated to be g(th)=2.000 889 909(51) improving the accuracy to 2.5×10(-8) due to the first rigorous evaluation of the two-photon exchange correction. The measured value is in excellent agreement with the theoretical prediction and yields the most stringent test of bound-state QED for the g factor of the 1s(2)2s state and the relativistic many-electron calculations in a magnetic field.
