摘要：

Radiative corrections to the Zemach contribution of the hydrogen hyperfine splitting are calculated. Their contributions amount to -0.63(3) ppm to the HFS. The radiative-recoil corrections are estimated to be 0.09(3) ppm and the heavy particle vacuum polarization shifts the HFS by 0.10(2) ppm. The status of the nuclear-dependent contributions is considered. From the comparison of theory and experiment a proton polarizability contribution of 3.5(9) ppm is found. The large shift from an earlier result (0.48(56) ppm) is due to using a more recent proton radius for the Zemach term calculation. The nuclear structure-dependent corrections to the difference nu(HFS)(1s) - n(3) nu(HFS)(ns) are also obtained.
