Abstract
The measurement of an excess in the cosmic-ray electron spectrum between 300
and 800 GeV by the ATIC experiment has - together with the PAMELA detection of
a rise in the positron fraction up to 100 GeV - motivated many interpretations
in terms of dark matter scenarios; alternative explanations assume a nearby
electron source like a pulsar or supernova remnant. Here we present a
measurement of the cosmic-ray electron spectrum with H.E.S.S. starting at 340
GeV. The H.E.S.S. data with their lower statistical errors show no indication
of a structure in the electron spectrum, but rather a power-law spectrum with
spectral index of 3.0 +- 0.1 (stat.) +- 0.3 (syst.) which steepens at about 1
TeV.
