Experiment: E93-031 CLAS experiment, 2000

Spokespersons: E. Anciant

Measurement comment: The differential PHI photoproduction cross section. The errors shown are the qu adratic sum of the statistics and the systematic uncertainties which include 3 PCT for normalization, 5 PCT for acceptance and 5-15 PCT for background subtraction
