Electromagnetic polarizabilities of nucleons bound in 12C and 16O

Abstract The polarizabilities of nucleons imbedded in 12C and 16O nuclei are measured via Compton scattering of 61 and 77 MeV photons, leading to α N = (11.5±0.8±2.1) × 10 −4 fm 3 and β N = (2.5∓0.8∓2.1) × 10 −4 fm 3 in close agreement with the free-nucleon values.
