Abstract
CRAWFORD1 has suggested that the bursts of γ-ray energy that correspond to positron annihilation at rest (0.511 MeV), which have been observed by Ashby and Whitehead2, may be caused by extensive air showers (EAS) of primary energy E0 ≈ 1016 eV. We present two major objections to that hypothesis.
