Abstract
The Isotope Matter Antimatter Experiment (IMAX) has detected 16 antiprotons,
in the energy range from 0.2 to 3.2 GeV. This result provides significant
improvement in statistical accuracy over previous cosmic ray antiproton
measurements in the same energy range. This measurement has been corrected for
instrumental and atmospheric losses, yielding top-of-the-atmosphere antiproton to
proton ratios in three energy intervals. These results are consistent with recent
theoretical predictions in which antiprotons are produced as secondary cosmic rays
and are transported through the galaxy according to the standard Leaky Box model.
