Nuclear-size corrections of order (Z{alpha}){sup 5} and (Z{alpha}){sup 6} to the S-state levels of hydrogenic atoms are considered. These nuclear-elastic contributions are somewhat smaller than the polarizability (nuclear-inelastic) corrections for deuterium, but are of comparable or larger size for the hydrogen case. For deuterium the (attractive) nonrelativistic (Z{alpha}){sup 5} correction to the 2S-1S transition is 0.49 kHz, while the (repulsive) relativistic (Z{alpha}){sup 6} contribution is {minus}3.40 kHz. For the proton the corresponding corrections are 0.03 kHz and {minus}0.61 kHz, respectively. The (Z{alpha}){sup 5} contribution largely cancels the Coulomb-retardation part of the nuclear-polarization correction. {copyright} {ital 1997} {ital The American Physical Society}
