    "abstract": "We study two-photon exchange for elastic electron-proton scattering at low\nQ^2. Compact approximate formulae for the amplitudes are obtained. Numerical\ncalculations are done for Q^2 \u003c 0.1 GeV^2 with several realistic form factor\nparameterizations, yielding similar results. They indicate that the corrections\nto magnetic form factor can visibly affect cross-section and proton radii. For\nlow-Q^2 electron-neutron scattering two-photon exchange corrections are shown\nto be negligibly small.",
