Abstract

The 113-m2 water Cherenkov detector at a depth of 1480 m (4200 m water equivalent) in the Homestake Gold Mine, Lead, South Dakota, has been used to study multiple muons with Eμ2.7 TeV produced in cosmic-ray interactions by primaries of 1014-1015 eV/nucleon. The decoherence curve and multiple-muon rates are presented. © 1983 The American Physical Society.
