Abstract
Cross sections for quasi-free Compton scattering from the deuteron were measured for incident energies of 236-260 MeV at the laboratory angle -135 degrees. The recoil nucleons were detected in a liquid-scintillator array situated at 20 degrees. The measured differential cross sections were used, with the the calculations of Levchuk et al., to determine the polarizabilities of the bound nucleons. For the bound proton, the extracted values were consistent with the accepted value for the free proton. For the bound neutron, the polarizabilities were determined to be alpha_n = 16.0 (+7.2, -6.7) and beta_n = -0.8 (-7.2, +6.7).
