Neutron Polarizabilities Investigated by Quasifree Compton Scattering from the Deuteron

Abstract

Measuring Compton scattered photons and recoil neutrons in coincidence, quasifree Compton scattering by the neutron has been investigated at MAMI (Mainz) at [Formula presented] in an energy range from 200 to 400 MeV. From the data a polarizability difference of [Formula presented] in units of [Formula presented] has been determined. In combination with the polarizability sum [Formula presented] deduced from photoabsorption data, the first precise results for the neutron electric and magnetic polarizabilities, [Formula presented] and [Formula presented], are obtained. © 2002 The American Physical Society.
