The A2 Collaboration at MAMI performs a manifold research program with real photons at the MAMI accelerator facility in Mainz (Germany) with the Crystal Ball/TAPS setup which, providing almost complete coverage in solid angle, is well suited for the detection and the identification of multi-particle final states.
In particular, the internal structure of the nucleon is studied via measurements of unpolarized cross sections and various polarization observables both in Compton scattering and meson photoproduction reactions reactions. These experiments make use of high-intensity unpolarized, linearly or circularly polarized photon beams, and unpolarized or polarized targets.
In this presentation, recent results from the Compton scattering and baryon spectroscopy programs are presented.
