Abstract
Fixed- subtracted dispersion relations are presented for Compton scattering off the nucleon at energies MeV, as a formalism to extract the nucleon polarizabilities from the data with a minimum of model dependence. The scalar polarizabilities difference and the backward spin polarizability enter directly as fit parameters in this formalism.
