Elastic And Inelastic Compton Scattering From Deuterium At 61 Mev, Danula Godagama
Elastic And Inelastic Compton Scattering From Deuterium At 61 Mev, Danula Godagama
Theses and Dissertations--Physics and Astronomy
A Compton scattering experiment using deuteron as target nuclei was carried out at the HIγS free electron laser facility at Durham, NC, with the goal of extracting the electromagnetic scalar polarizabilities of the neutron, αn and βn. A beam of 61~MeV gamma photons with a narrow energy spread was incident on a liquid deuterium target. The scattered gamma rays were detected at three scattering angles, 55o, 115o and 150o. Backward-scattered gamma rays were detected using two large-volume NaI spectrometers with energy resolution (σE/E) better than 2%. The combined effect of …

The electromagnetic polarizabilities of the nucleon are fundamental properties that describe its response to external electric and magnetic fields. They can be extracted from Compton-scattering data—and have been, with good accuracy, in the case of the proton. In contradistinction, information for the neutron requires the use of Compton scattering from nuclear targets. Here, we report a new measurement of elastic photon scattering from deuterium using quasimonoenergetic tagged photons at the MAX IV Laboratory in Lund, Sweden. These first new data in more than a decade effectively double the world data set. Their energy range overlaps with previous experiments and extends …

Elastic scattering of photons from 12C has been investigated using quasimonoenergetic tagged photons with energies in the range 65–115 MeV at laboratory angles of 60∘, 120∘, and 150∘ at the Tagged-Photon Facility at the MAX IV Laboratory in Lund, Sweden. A phenomenological model was employed to provide an estimate of the sensitivity of the 12C(γ,γ)12C cross section to the bound-nucleon polarizabilities.
