Description

The new function, making it possible to more accurately describe the spatial distribution of the Cherenkov light, is applied for the EAS parameters restoration. The differential energy spectrum of the primary cosmic rays within the energies range from 0.6 up to 50 PeV with improved energy distribution is presented. The average mass composition of the primary cosmic rays is evaluated. The above mass composition practically does not depend on the energy within the range from 1015 up to 1016 eV. Fast composition weighting is observed by further energy growth

Abstract (Russian)

Для восстановления параметров ШАЛ применена новая функция, позволяющая более точно описывать пространственное распределение черенковского света. Представлен дифференциальный энергетический спектр первичных космических лучей в диапазоне энергий от 0.6 до 50 ПэВ с улучшенным энергетическим разрешением. Оценен средний массовый состав первичных космических лучей. Массовый состав практически не зависит от энергии в диапазоне от 1015 до 1016 эВ. При дальнейшем росте энергии наблюдается быстрое утяжеление состава
