Primary cosmic-ray spectrum at energies ∼(1013÷1016) eV from multiple muon events in NUSEX experiment

  • Published:
Il Nuovo Cimento C

Summary

The multiple-muon rates measured in the NUSEX experiment at a vertical depth of 5000 hg/cm2 s.r. are compared with some current models of the primary cosmic-ray composition. Monte Carlo simulations as well as analytical formulae which take into account the geometrical and acceptance features of the apparatus have been used in calculations. A good agreement is found with a model in which the relative fraction of primary heavy nuclei does not increase significantly up to about 1016 eV. This model reproduces very well both the all-nucleon flux measured in the range (1013÷1014) eV and the all-particle spectrum up to 1016 eV.

Riassunto

Le frequenze di muoni multipli ottenute con il rivelatore NUSEX ad una profondità verticale di 5000 hg/cm2 sono confrontate con diversi modelli sulla composizione di primari cosmici. Questo studio è fatto usando Montecarlo e formule analitiche che tengono conto degli aspetti geometrici e dell'accettanza dell'apparato. Un buon accordo è trovato con un modello nel quale la relativa frazione di nuclei pesanti non cresce significatamente fino a 1016 eV. Questo modello riproduce bene sia il flusso totale di nuclei misurato nell'intervallo (1013÷1014) eV che lo spettro di particelle fino a 1016 eV.

Резюме

Интенсивности множественных мюонных событий, измеренных в NUSEX эксперименте на глубине 5000 hg/cm2 s.r., сравниваются с имеющимися моделями первичного состава космических лучей. При вычислениях используются моделирования по методу Монте-Карло и аналитические формулы, которые учитывают геометрические характеристики аппаратуры. Получается хорошее согласие с моделью, в которой относительная доля первичных, тяжелых ядер существенно не увеличивается вплоть до энергий 1016 эВ. Эта модель очень хорошо воспроизводит поток всех нуклонов, измеренных в области (1013÷1014) эВ, и спектр всех частиц вплоть до 1016 эВ.
