Tr. Hemmert et al., COMPTON-SCATTERING AND THE SPIN STRUCTURE OF THE NUCLEON AT LOW ENERGIES, Physical review. D. Particles and fields, 57(9), 1998, pp. 5746-5754
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.
