Summary
Response functions for underground muons are obtained by solving numerically the equations of hadronic cascades in the atmosphere, by assuming Feynman scaling for hadronic interactions over the whole energy region. For practical use of the response functions in cosmic-ray modulation study, calculations are made for various combinations of parameters such as zenith angle, atmospheric depth and muon threshold energy. The present response functions are consistent with cosmic-ray measurements and can be well utilized for the study on the cosmic-ray modulation.
Riassunto
Si ottengono funzioni di risposta per muoni sotterranei risolvendo numericamente le equazioni per le cascate adroniche nell'atmosfera, assumendo lo scaling di Feynman per interazioni adroniche nell'intera regione di energia. Per l'uso pratico di funzioni di risposta nello studio di modulazione dei raggi cosmici, si fanno calcoli per varie combicazioni di parametri come l'angolo di zenit, la profondità atmosferica e l'energia muonica di soglia. Le attuali funzioni di risposta sono coerenti con le misurazioni dei raggi cosmici e possono essere bene utilizzate per lo studio della modulazione dei raggi cosmici.
