Abstract
We analyze polarized Compton scattering which provides information on the spin-structure of the nucleon. For scattering processes with photo n energies up to 100 MeV the spin-structure dependence can be encoded into four independent parameters-the so-called spin-polarizabilities g amma(i), i = 1,...,4, of the nucleon, which we calculate within the fr amework of the ''small scale expansion'' in SU(2) baryon chiral pertur bation theory. Specific application is made to ''forward'' and ''backw ard'' spin-polarizabilities.
