Abstract
The effect of deuteron structure on the hyperfine structure of deuterium is reexamined by using several realistic nucleon-nucleon (NN) potentials. We find that the value of the Bohr-Low correction is almost the same for all the potentials considered, and is larger than the value obtained by Low and by Low and Salpeter by using much simpler potentials. Among other corrections to the hyperfine structure, the most important one is due to angular momentum (L) dependent terms in the NN potential. This correction is sensitive to the choice of the potential. When these other corrections are included, theory and experiment become compatible for some of the potentials, while the situation is worsened for others. However, there are remaining ambiguities related to mesonic and isobaric effects, the implications of which are discussed.
