    "abstract": "We reconsider the Dirac-Foldy contribution $\\mu^2/m$ to the neutron electric\npolarizability. Using a Dirac equation approach to neutron-nucleus scattering,\nwe review the definitions of Compton continuum ($\\bar{\\alpha}$), classical\nstatic ($\\alpha^n_E$), and Schr\\\"{o}dinger ($\\alpha_{Sch}$) polarizabilities\nand discuss in some detail their relationship. The latter $\\alpha_{Sch}$ is the\nvalue of the neutron electric polarizability as obtained from an analysis using\nthe Schr\\\"{o}dinger equation. We find in particular $\\alpha_{Sch} =\n\\bar{\\alpha} - \\mu^2/m$ , where $\\mu$ is the magnitude of the magnetic moment\nof a neutron of mass $m$. However, we argue that the static polarizability\n$\\alpha^n_E$ is correctly defined in the rest frame of the particle, leading to\nthe conclusion that twice the Dirac-Foldy contribution should be added to\n$\\alpha_{Sch}$ to obtain the static polarizability $\\alpha^n_E$.",
