Measurement of the neutron flux produced by cosmic ray muons with LVD at Gran Sasso

The flux of muon-produced neutrons far away from the muon track may constitute a background for the underground detectors searching for rare events. The muon events collected by the first LVD tower from March, 1996, to February, 1998, (1.56 years of live time) were used to estimate the neutron flux at various distances from the muon track or muon-produced cascade.
