【 摘 要 】

Atmospheric neutrinos are produced in interactions of cosmic rays with atomic nuclei in the Earths atmosphere. In low energy neutrino experiments they are mainly considered as a background for studied processes. For atmospheric neutrinos in sub-GeV range we present semi-analytical expected yield for four neutrino detection reactions: νe-ES, νp-ES, inverse β-decay and12C(ν, ν′)12C∗(15.11 MeV), as well as results of Monte-Carlo simulation for other ν12C interaction channels. Calculations are made for 4 neutrino experiments and include neutrino oscillation averaged over neutrino arrival directions.
