Phys. Rev. Lett. 75, 4728–4731 (1995)New Value of the α3 Electron Anomalous Magnetic MomentReceived 4 October 1995; published in the issue dated 25 December 1995 Highly accurate numerical evaluation of the sixth-order term of the electron anomalous magnetic moment ae has detected an error in the analytic value of a fourth-order infrared-divergent integral, which is needed to obtain the best estimate of the α3 term as a combination of analytic values of 67 Feynman diagrams and numerical values of 5 diagrams for which no analytic results are known. Correction of this error leads to a small but significant revision of the α3 term. As a consequence the fine structure constant α determined from theory and experiment of ae is reduced by 55×10-9. © 1995 The American Physical Society URL:
