Polarization Measurements in High-Energy Deuteron Photodisintegration
We present measurements of the recoil proton polarization for the d(→γ,→p)n reaction at θc.m.=90° for photon energies up to 2.4 GeV. These are the first data in this reaction for polarization transfer with circularly polarized photons. The induced polarization py vanishes above 1 GeV, contrary to meson-baryon model expectations, in which resonances lead to large polarizations. However, the polariz
