Abstract

The g factor of lithiumlike silicon ²⁸Si¹¹⁺ 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 1s²2s state and the relativistic many-electron calculations in a magnetic field.
