Is there an excees of electron neutrinos in the flux in the atmosphere?
Ryazhskaya O.G.
The background caused in Cerenkov detectors by isolated neutrons during the detection of neutrinos in the atmosphere is discussed. The neutrons are generated in nuclear showers initiated by muons in the earth around the detectors. Incorporating events associated with the detection of π° mesons which are produced in nA—>тт°Х reactions and which simulate the detection of ve leads to a measured ratio Ι(νμ)/Ι(νε) which is close to that expected for the energy range 0.2-5 GeV. © 1994 American Institute of Physics.
