摘要：

We report on a search for electro-magnetic and/or hadronic showers (cascades) induced by high-energy neutrinos in the data collected with the AMANDA II detector during the year 2000. The observed event rates are consistent with the expectations for atmospheric neutrinos and muons. We place upper limits on a diffuse flux of extraterrestrial electron, tau and muon neutrinos. A flux of neutrinos with a spectrum Phi proportional to E-2 which consists of an equal mix of all flavors, is limited to E(2)Phi(E) = 8.6 x 10(-7) GeV cm(-2)s(-1) sr(-1) at a 90% confidence level for a neutrino energy range 50 TeV to 5 PeV. We present bounds for specific extraterrestrial neutrino flux predictions. Several of these models are ruled out. (C) 2004 Elsevier B.V. All rights reserved.
