Helicity-dependent cross sections for the photoproduction of $\ddot{I}{€}^0$ pairs from nucleons

M. Dieterle, L. Witthauer, A. Fix +88

The double-polarization observable $E$ and helicity-dependent cross sections $\ddot{I}{ƒ}_{1/2}$, $\ddot{I}{ƒ}_{3/2}$ have been measured for the photoproduction of $\ddot{I}{€}^0$ pairs off quasi-free proton…
