Accurate determination of the fine structure constant and test of QED

We report a new measurement of atomic recoil using atom interferometry and Bloch oscillations in a vertical accelerated optical lattice. The new deduced value of the fine structure constant is α^-1=137.035 999 037(91) with a relative uncertainty of 6.6×10^-10. Using this determination, the theoretical value of the electron anomaly ae is 0.001 159 652 181 13(84). This value is in agreement with the experimental determination of Gabrielse 0.001 159 652 180 73(28). This comparison provides the stringest test of QED, the accuracy is good enough to test for the first time the muonic and hadronic contributions to a_e.
