Observations on extensive air showers III. The distribution of charged particles

Abstract

The distribution of charged particles in air showers containing 3 × 10⁶, 3 × 10⁷ and 10⁸ particles at sea level has been measured and compared with theoretical calculations by Nishimura and Kamata. The best value of the age parameter S appears to be 1·4. The significance of this result is briefly discussed.
