The Compton-scattering program at the Tagged Photon Facility at the MAX IV Laboratory is primarily focused on the extraction of the nucleon isoscalar polarizabilities from the 2 H(γ, γ) reaction. In addition to deuterium, measurements have been conducted on 6 Li, 12 C, and 16 O for the purposes of understanding experimental systematics. At this time, we have preliminary cross sections for 12 C(γ, γ) that agree with previously published results. This is a critical first step in establishing our understanding of the absolute normalization of our experiment that is neccessary before reporting 2 H(γ, γ) results.

“…The most recent interpretations of 12 C(γ,γ) crosssection data [12,13] utilize multiple Lorentzian lineshapes to construct the E1 scattering amplitude. However, in our analysis, the phenomenological model is unable to fit the low-energy data of Wright et al [9] using these lineshapes (see Fig.…”

“…The Lorentzian L QD (E) has the parameters E QD , Γ QD , and σ QD given in Table II, with E t = 40 MeV and ∆E = 10 MeV. Since the analysis of Warkentin et al [13] indicated that the extraction of α eff and β eff depends only slightly on the parametrization of the QD amplitude, only the above parametrization will be used in this analysis.…”

A multitude of Compton-scattering experiments have been carried out with a variety of light nuclei (see Table I) for the purpose of determining the bound-nucleon polarizabilities (α eff and β eff ) given by α eff = α N + ∆α, β eff = β N + ∆β, (6) where α N and β N are the nucleon-averaged free polarizabilities and ∆α and ∆β represent the nuclear modifications [13] which can be extracted from the scattering data.…”

These data sets have been analyzed using a model that parametrizes the Compton-scattering amplitude in terms of the photoabsorption cross section, its multipole decomposition and the bound-nucleon polarizabilities.…”

Elastic scattering of photons from12 C has been investigated using quasi-monoenergetic 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 12 C(γ,γ) 12 C cross section to the bound-nucleon polarizabilities.
