An interpretation of cosmic-ray jets

Abstract

A frequency function of multiplicity and dispersion of the log tan θ plot of the secondary particles of cosmic-ray jets is derived and compared with the experimental results. On the basis of this distribution law together with the "isobar-fireball" model, the characteristic features of cosmic-ray jets are discussed. The predictions and validity of this model for jets of energy 1013 to 1016 eV are examined in the light of experiments, and a possible change in the characteristic feature of jets around 1016 eV energy is suggested.
