Abstract: (IOP)

The solar neutrino experiment Borexino, which is located inthe Gran Sasso underground laboratories, is in a unique position tostudy muon-induced backgrounds in an organic liquid scintillator. Inthis study, a large sample of cosmic muons is identified and trackedby a muon veto detector external to the liquid scintillator, and bythe specific light patterns observed when muons cross thescintillator volume. The yield of muon-induced neutrons is found tobe Yn = (3.10±0.11)·10−4 n/(μ·(g/cm2)). The distance profile between the parent muontrack and the neutron capture point has the average valueλ = (81.5±2.7) cm. Additionally the yields of a number ofcosmogenic radioisotopes are measured for 12N, 12B,8He, 9C, 9Li, 8B, 6He, 8Li, 11Be,10C and 11C. All results are compared with Monte Carlosimulation predictions using the FLUKA and GEANT4 packages.General agreement between data and simulation is observed for thecosmogenic production yields with a few exceptions, the mostprominent case being 11C yield for which both codes returnabout 50% lower values. The predicted μ-n distance profileand the neutron multiplicity distribution are found to be overallconsistent with data.
