Indirect Dark Matter Search: Cosmic Positron Fraction Measurement from 1 to 50 GeV with AMS-01
Henning Gast, Jan Olzem, Stefan Schael
A new measurement of the cosmic ray positron fraction in the energy range of 1-50 GeV is presented. The measurement is based on data taken by the AMS-01 experiment during its 10 da…
