摘要

The total cross section has been measured for ω meson photoproduction on the proton for the center-of-mass energy √(s) ranging from 1.69 to 1.75 GeV. Including the subthreshold region of ω photoproduction, a set of about 40 data points has been obtained with a fine energy step of 1–2 MeV. The data set enables us to deduce the ω - N scattering length.
