abstract = {Differential cross-sections for Compton scattering from the
proton hal e been measured at the MAMI tagged photon
facility using the TAPS setup. The data cover an angular
range of theta (lab)(gamma) = 59 degrees -155 degrees and
photon energies ranging from 55 MeV to 165 MeV. Our results
are in good agreement with those from previous experiments,
but yield higher precision. Using dispersion relations the
proton polarizabilities have been determined to be
<(<alpha>)over bar> = [11.9 +/- 0.5(stat.) -/+ 1.3(syst.)
+/- 0.3(mod.)] (.) 10(-4) fm(3) and <(<beta>)over bar> =
[1.2 +/- 0.7(stat.) +/- 0.3(syst). +/- 0.4(mod.))] (.)
10(-4) fm(3). These results confirm the Baldin sum rule
which was re-evaluated to be <(<alpha>)over bar> +
<(<beta>)over bar> = [13.8 +/- 0.4] 10(-4) fm(3). We can
also conclude that there is no significant additional
asymptotic contribution to the backward spin polarizability
gamma (pi) beyond the t-channel pi (0)-exchange.},
