Abstract

A series of experiments were performed at the Tagged Photon Facility at MAX-lab in Lund, Sweden to study photon scattering from the deuteron and extract the neutron polarizabilities. The deuteron Compton scattering cross section was measured at laboratory angles of $60^o$, $120^o$, and $150^o$ for photon energies from 70 - 112 MeV. The photons were scattered from the Lund liquid deuterium target and detected in three large (20'' x 20'') NaI photon spectrometers. These detectors have sufficient energy resolution ($\sim$2$\%$ at 100 MeV) to separate the elastically and inelastically scattered photons. The extracted scattering cross section for this experiment was found to have angular distributions that matched prior experiments but needed a scaling factor to bring the absolute cross section into agreement. This scaling factor was determined to have a value of 1.47 $\pm$ 0.10. Suggestions are made for future studies that could yield further knowledge of the scaling factor and potentially allow for this data to be re-normalized.
