Summary
An experiment has been carried out to investigate the variation of vertical cosmic-ray intensity with depth in the range (800÷8400) m w.e. Counter telescopes with plastic scintillator layers and Geiger counter trays, kept in the horizontal plane and in coincidence, were employed. The experiment was carried out in the Kolar Gold Fields (Mysore State, India). The results obtained at depths of 816, 1812, 3410, 4280, 6380 and 8400 m w.e. are given.
Riassunto
Si è effettuato un esperimento per studiare la variazione dell’intensità verticale dei raggi cosmici nell’intervallo (800÷8400) m a.e. Si sono adoperati telescopi di contatori con strati di scintillatori plastici e vassoi di contatori di Geiger posti orizzontalmente e in coincidenza. L’esperimento fu eseguito nei Kolar Gold Fields (Stato di Mysore). Si riportano i risultati ottenuti alle profondità di 816, 1812, 3410, 4280, 6380 e 8400 m a.e.
