Abstract / Description:A new independent value for the electron's mass in units of the atomic mass unit is presented, m e = 0.0005485799092(4) u. The value is obtained from our recent measurement of the g factor of the electron in 12C5+ in combination with the most recent quantum electrodynamical (QED) predictions. In the QED corrections, terms of order α² were included by a perturbation expansion in Zα. Our total precision is three times better than that of the accepted value for the electron's mass.
