Abstract: (Elsevier)
We present the results of observation of the Geminga pulsar carried out in the TeV energy band during the 6 year period spanning 2000-2006 using the Pachmarhi Array of Cherenkov Telescopes (PACT). A long stretch of data, new computer codes and the ''Tempo'' package have been used in the present analysis. We have searched for evidence of pulsed emission of @c-rays from the Geminga pulsar using the post-glitch pulsar elements obtained by Jackson and Halpern from X-ray/@c-ray satellite data. We do no t see any significant evidence for pulsed emission from the Geminga pulsar at a threshold energy of 825GeV. In this paper we present our results on the light curve in the TeV energy band, set an upper limit on the time averaged flux of @c-rays, and compar e our results with other ground based observations.- gamma ray: emission
