Phys. Rev. Lett. 88, 011603 (2001) [4 pages]New Determination of the Electron’s MassReceived 29 August 2001; published 19 December 2001 A new independent value for the electron’s mass in units of the atomic mass unit is presented, me = 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. © 2002 The American Physical Society URL:
