Query: Investigating Neutron Polarizabilities through Compton Scattering on
  $^3$He   We examine manifestations of neutron electromagnetic polarizabilities in
coherent Compton scattering from the Helium-3 nucleus. We calculate $\gamma
^3$He elastic scattering observables using chiral perturbation theory to
next-to-leading order (${\mathcal O}(e^2 Q)$). We find that the unpolarized
differential cross section can be used to measure neutron electric and magnetic
polarizabilities, while two double-polarization observables are sensitive to
different linear combinations of the four neutron spin polarizabilities.
