The pions subsequently decay to produce muon neutrinos. We find that the energy spectrum of muon neutrinos consists of a sharp rise at $\sim 50$ TeV, corresponding to the onset of the resonance, above which the flux drops as $ε_ν^{-2}$ up to an upper-energy cut-off that is determined by either kinematics or by the maximum energy to which protons are accelerated. We predict event rates as high as 10-50 km$^{-2}$ yr$^{-1}$ from relatively young, close neutron stars. Such fluxes would be detectable by IceCube.6 pages, 2 figures, to be published in the proceedings of the CRIS 2006 conference, Catania, Italy, May 29 - June 2, 2006Astrophysicstext
