The helicity amplitudes A${}_{1/2}$ and A${}_{3/2}$ for the D${}_{13}(1520)$ resonance obtained from the $\vec{\gamma }\vec{p}\to p{\pi }^0$ reaction}

Abstract

The helicity dependence of the $\vec{\gamma }\vec{p}\to p{\pi }^0$ reaction has been measured for the first time in the photon energy range from 550 to 790 MeV. The experiment, performed at the Mainz microtron MAMI, used a 4$\pi$-detector system, a circularly polarized, tagged photon beam, and a longitudinally polarized frozen-spin target. These data are predominantly sensitive to the $D_{13}(1520)$ resonance and are used to determine its parameters.
