Abstract
In 1996-1997, the Geminga pulsar was observed at the Crimenn Astrophysical Observatory with a ground-based gamma-ray telescope. An analysis of the obs ervational data suggests that this object is a source of ultrahigh-energy g amma rays. An analysis of the temporal distribution of gamma-ray photons by an epoch-folding technique reveals a periodicity in the gamma-ray emission with a period of 0.237 s.
