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.…”
