High Energy Hadrons in Atmospheric Cosmic Rays Observed with Fe Emulsion Chambers
- Received Date: 1989-01-30
Abstract: A part of K4 (1984-1985) Fe emulsion chambers exposed at Mt Kanbala (altitude 5500 m, atmospheric depth 520 g/cm2) by China-Japan Emulsion Chamber Collaboration has been analyzed with systematic scanning and measurement The distribution of the starting depths of the observed showers is given. The zenith angle distribution, vertical intensity, energy spectrum and attenuation length of hadrons in air and in iron are presented. Our results are compared with the recent data given by other experiments, and they are approximately consistent with each other.
