英文摘要 | 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 gamma = -3.170 +/- 0.008(stat + syst) +/- 0.008(energy scale). |
