Abstract
DESY-HERA. Measurement of the inclusive cross section for JET production inphotoproduction events in E+ P interactions. JETS are defined by a cone in the (etarap-phi) plane.. Data are taken with a 27.5 GeV positron beam and 820 GeV proton beam. The photoproduction region is defined by Q**2 & lt; 4 GeV**2. W is the virtuality of thephoton.
