Compton scattering from the deuteron and extracted neutron polarizabilities
(2003) In Physical Review Letters 90(19). Abstract
 Differential cross sections for Compton scattering from the deuteron were measured at MAXLab for incident photon energies of 55 and 66 MeV at nominal laboratory angles of 45degrees, 125degrees, and 135degrees. Tagged photons were scattered from liquid deuterium and detected in three NaI spectrometers. By comparing the data with theoretical calculations in the framework of a onebosonexchange potential model, the sum and the difference of the isospinaveraged nucleon polarizabilities, alpha(N) + beta(N) = 17.4 +/ 3.7 and alpha(N)  beta(N) = 6.4 +/ 2.4 (in units of 10(4) fm(3)), have been determined.

By combining the latter with the globalaveraged value for alpha(p)  beta(p) and using the predictions of the Baldin sum rule for the sum of the nucleon polarizabilities, we have obtained values for the neutron electric and magnetic polarizabilities of alpha(n) = 8.8 +/ 2.4(total) +/ 3.0(model) and beta(n) = 6.5 /+ 2.4(total) /+ 3.0(model), respectively.
