Goal of this work is the consistent theoretical description of Compton scattering from the single nucleon and the deuteron. Besides the Compton cross sections, our main concern is with the nucleon polarizabilities. Experimentally, only a few of these quantities are known. Especially our knowledge of the neutron polarizabilities is not satisfying. Therefore, we contribute to this ongoing discussion by fitting the average over proton and neutron polarizabilities to the elastic deuteron Compton-scattering data. Similarly, we determine the proton polarizabilities from fits to the proton data. We finally combine both results in order to identify the neutron polarizabilities.
