Ratio of Neutral to Charged Particles in the Nuclear Interacting Component of Cosmic Rays

Abstract

The ratio of neutral to charged primaries of nuclear interactions having a median primary energy around ${10}^{11}$ ev has been measured at 3250-m elevation, the result being $\frac{N}{C}\cong \frac{3}{4}$. This value indicates a high degree of elasticity in the nuclear collisions from which nucleons of ${10}^{11}$-ev emerge.
