  "abstract": "Elastic and inelastic Compton-scattering cross sections of the deuteron were measured at HI$γ$S using a circularly polarized, quasi-monoenergetic $γ$-ray beam (61.0 MeV). Scattered $γ$ rays from a liquid deuterium target were detected at $55^\\circ$, $115^\\circ$, and $150^\\circ$. High-resolution NaI(Tl) detectors at backward angles enabled separation of elastic and inelastic events. A $χ$EFT analysis of the data yields new neutron scalar polarizabilities, $α^n_{E1} = 12.25 \\pm 1.1\\mathrm{(stat)} \\pm 0.3\\mathrm{(BSR)} \\pm 0.8\\mathrm{(th)}$ and $β^n_{M1} = 2.95 \\mp 1.1\\mathrm{(stat)} \\mp 0.3\\mathrm{(BSR)} \\mp 0.8\\mathrm{(th)}$ (in units of $10^{-4} \\mathrm{fm}^3$) reducing statistical uncertainties by 12 %.",
