The nue- --> pi- pi0 and nu e+ --> pi+ pi0 reaction have a resonant structure whenever the energy of the s--channel equals the mass of a JP=1- vector meson. The resonant cross sections are of the order 10-38 cm2 and correspond to cosmic ray antineutrino energies in the range 0.2 to 2 TeV. A similar structure occurs in the annihilation of cosmic ray antineutrinos with a relic (background) neutrino. For mnu <= 10-3 eV the resonant energy is above GZK limit and their decay products include multiple gamma--rays. Possible detection schemes are discussed, especially those which rely on Cherenkov radiation.
