Investigation of extensive air showers containing nuclear active particles

Abstract

The exponent of the density spectrum of the electronic component of extensive air showers containing nuclear active particles was determined to be γ=1.34±0.08 assuming that the density of nuclear active particles is proportional to the density of electrons in air showers. The agreement of the exponent found in the present experiment with that determined earlier for extensive air showers ( γ=1.34±0.02) with the same arrangement, which however, consisted only of the electron detectors supports the above assupmtion. From this it follows that the density spectrum of nuclear active particles has the form of a power law with an exponent approximately equal to γ. Furthermore, the decoherence curve between the electron and nuclear active particle detectors was measured. The experimental results are briefly discussed.
