Elastic photon scattering from deuterium

Abstract

Tagged photons in the energy range 'E'ã = 84.3-104.5 MeV were scattered elastically from liquid deuterium and detected in the large volume Boston University NaI (BUNI) spectrometer. The NaI detector has an energy resolution of ~2% at 100 MeV which was sufficient to separate the elastic and inelastic scattering contributions. A 5-point angular distribution covering the range [theta]ã = 35°-150° was measured. Using a modified impulse approximation calculation in addition to a rigorous calculation done by Levchuk, estimates of the nucleon polarizabilities in the deuteron were obtained.
