摘要：

Neutrinos with energy greater than GeV are copiously produced in the p (A, p) interactions occurring in several astrophysical sites such as (i) the Earth atmosphere, (ii) our galactic plane as well as in (iii) the galaxy clusters. A comparison of the tau and nut neutrino flux in the presence of neutrino oscillations from these three representative astrophysical sites is presented. It is pointed out that the non-atmospheric tau neutrino flux starts dominating over the downward going atmospheric tau neutrino flux for neutrino energy E as low as similar to 10 GeV. This energy value is much lower than the energy value, E greater than or equal to 5 x 10(4) GeV, estimated for the dominance of the non-atmospheric mu neutrino flux, in the presence of neutrino oscillations. Future prospects for possible observations of non-atmospheric tau neutrino flux are briefly mentioned. (C) 2004 Elsevier B.V. All fights reserved.
