英文摘要
The rocks in deep underground are exposed by high energy muon for long time and record an accumulation of muon induced cosmogenic nuclides of Be-10 and Al-26. We have measured the cross-sections of production rates of Be-10 and Al-26 for SiO2 plates using the muon beam with the energy of 160 Gev/c at CERN. Also, the efficiency was investigated for the extraction of SiO2 from granite rocks.
