Characteristics of EAS neutron component obtained with PRISMA-32 array

TL;DR

This study investigates the neutron component of extensive air showers using the PRISMA-32 array, analyzing neutron distribution, multiplicity spectrum, and shower ratios to understand cosmic ray interactions.

Contribution

It presents new measurements of the EAS neutron component using a dedicated array with $^{6}Li$ scintillators, providing detailed distribution functions and preliminary spectral data.

Findings

Lateral distribution function of neutrons in EAS determined

Preliminary neutron multiplicity spectrum obtained

Distribution of showers in e/n ratio analyzed

Abstract

The paper is devoted to the results of the EAS neutron component investigations by means of the PRISMA-32 array. The array consists of 32 en-detectors and enables to record delayed thermal neutrons accompanying showers. For registration of thermal neutrons, the scintillator based on $^{6}Li$ isotope as a target is used in the detectors. Some results of the processing of data accumulated over a long period of time are presented: the lateral distribution function of neutrons in EAS and preliminary results on EAS neutron multiplicity spectrum and distribution of showers in e/n ratio.
