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.\n  [Note added in 2018] An erratum for this paper has been posted as arXi","authors_text":"Andreas Nogga, Daniel R.
