Abstract

We present a measurement of the cosmic ray (e^+ + e^-) flux in the range 0.5 GeV to 1 TeV based on the analysis of 10.6 million (e^+ + e^-) events collected by AMS. The statistics and the resolution of AMS provide a precision measurement of the flux. The flux is smooth and reveals new and distinct information. Above 30.2 GeV, the flux can be described by a single power law with a spectral index γ = −3.170 +/- 0.008 (stat + syst) +/- 0.008 (energy scale)
