Abstract (from CDS):

The Crab and Geminga pulsars were observed with the HEGRA stereoscopic IACT-System. A search for phase-resolved time structure of TeV gamma emission was carried out for both pulsars. No evidence for pulsed emission was observed. Geminga shows up as a TeV quiet object in our data. Upper limits were derived in units of the observed DC TeV Crab flux. The 3σ upper limit on DC TeV emission of Geminga is 13.0% of the Crab flux. Upper limits on pulsed emission were derived for the phase intervals which revealed pulsed emission in the EGRET 30 MeV - 10 GeV data. The 3σ upper limits on pulsed emission in these phase intervals are <2.3% and <7.2% of the Crab DC flux for the Crab and Geminga pulsars, respectively.
