Abstract
We analyze polarized Compton scattering which provides information on the spin-structure of the nucleon. For scattering processes with photon energies up to 100 MeV the spin-structure dependence can be encoded into four independent parameters-the so-called spin-polarizabilities gamma_i, i=1...4 of the nucleon, which we calculate within the framework of the "small scale expansion" in baryon chiral perturbation theory. Specific application is made to "forward" and "backward" spin-polarizabilities.
