    "abstract": "We determine the third Zemach moment of hydrogen (\u003cr^3\u003e_(2)) using only the\nworld data on elastic electron-proton scattering. This moment dominates the O\n(Z alpha)^5 hadronic correction to the Lamb shift in muonic atoms. The\nresulting moment, \u003cr^3 \u003e_(2) = 2.71(13) fm^3, is somewhat larger than\npreviously inferred values based on models. The contribution of that moment to\nthe muonic hydrogen 2S level is -0.0247(12) meV.",
