Angular Dependence of Proton Polarization in the Reactionγd→pnand a Partial-Wave Analysis of Possible Dibaryon Resonances

Abstract

The angular dependence of proton polarization in $\gamma d\to \mathrm{pn}$ has been measured at photon energies between 400 and 650 MeV. The polarization and differential-cross-section data are consistently explained by introducing a dibaryon resonance $I\left(J^P\right)=0\left(3^{+}\right) or 0\left(1^{+}\right)$ at ≈ 2360 MeV.
