RESONANT SCATTERING OF ANTINEUTRINOS
A cosmic ray recorder operated for 21 days underground at a depth of 5050 mwe yielded no cosmic-ray events, which means that the meson flux is probably less than 0.5/m/sup 2/ day and there is probably no resonance in antineutrino scattering by electrons involving a virtual charged boson (muon) with a mass equal to that of a K meson.
