摘要：

We present an analysis of muon events with all muon multiplicities collected during 21804 h of operation of the first Large Volume Detector tower. The measured angular distribution of muon intensity has been converted to the "depth-vertical-intensity" relation in the depth range from 3 to 12 km w.e. The analysis of this relation allowed us to derive the power index gamma of the primary all-nucleon spectrum: gamma = 2.78 +/- 0.05. The "depth-vertical-intensity" relation has been converted to standard rock and the comparison with the data of other experiments has been done. We also present the derived vertical muon spectrum at sea level. [S0556-2821(98)00517-7].
