Abstract: Helicity dependent cross sections $\sigma_{1/2}$ and $\sigma_{3/2}$ of photoproduction of $\pi^{0}\pi^{0}$ meson pairs off quasi-free protons and off quasi-free neutrons in the second and third nucleon resonance region have been measured for the first time at the Mainzer Mikrotron (MAMI) electron accelerator facility. The knowledge of $\sigma_{1/2}$ and $\sigma_{3/2}$ will put stringent constraints on the different resonances that contribute to the nucleon excitation spectrum and will clearly help to improve its theoretical understanding.
