Title: Polarized Compton Scattering and Nucleon Spin Polarizabilities at the Upgraded HI{gamma}S Facility

Abstract

The HI{gamma}S facility is capable of providing intense beams of linearly and circularly polarized gamma rays, at energies from 2 MeV and soon to extend up to 100 MeV. This paper describes a Compton scattering program which has been designed to measure the electric and magnetic polarizabilities of the proton and the neutron, as well as the spin-polarizabilities of both. Linearly polarized beams will be used to measure the electric and magnetic polarizabilities of the proton, while Compton scattering from the deuteron will lead to values of these fundamental quantities for the neutron. Circularly polarized beams and polarized proton and {sup 3}He targets will be used to extract the four spin-polarizabilities of the nucleons with accuracies ranging from 5-to-25%. These values will be compared to the predictions of Chiral Perturbation Theory and anticipated results from Lattice QCD calculations.
