    "abstract": "Nuclear-size corrections of order $(Z \\alpha)^5$ and $(Z \\alpha)^6$ to the\nS-state levels of hydrogenic atoms are considered. These nuclear-elastic\ncontributions are somewhat smaller than the polarizability (nuclear-inelastic)\ncorrections for deuterium, but are of comparable or larger size for the\nhydrogen case. For deuterium the (attractive) nonrelativistic $(Z \\alpha)^5$\ncorrection to the 2S-1S transition is 0.49 kHz, while the (repulsive)\nrelativistic $(Z \\alpha)^6$ contribution is -3.40 kHz. For the proton the\ncorresponding corrections are 0.03 kHz and -0.61 kHz, respectively. The $(Z\n\\alpha)^5$ contribution largely cancels the Coulomb-retardation part of the\nnuclear-polarization correction.",
