Abstract
The emulsion chamber experiment PAMIR at high mountain altitude (4370m a.s.l.) registers hadronic and electromagnetic secondary particles of cosmic rays with a high threshold energy in the TeV region. These particles are produced preferentially in the extreme forward direction of interactions of cosmic ray protons or Helium nuclei in the atmosphere with primary energies mainly below 1 PeV. Hence the measurements are sensitive to the physics of high-energy hadronic interaction models as implemented in the Monte Carlo air shower simulation program CORSIKA. By use of detailed detector simulations we compare data of the PAMIR experiment with predictions of different models for the energy spectrum of the electromagnetic component.
