Abstract
Recent experiments with atomic clocks and hydrogen gas samples have
shown discrepancies between theory and experiment. There are serious
disagreements with respect to four different parameters: two different
frequency shift parameters and a line broadening cross section relating
to the H maser, and a longitudinal relaxation rate observed in a
hydrogen gas sample. We study the changes in the short-range singlet and
triplet potentials that would be needed to eliminate the above
discrepancies. We find that no such changes can remove all four
discrepancies simultaneously. In addition, we investigate a possible
role of spin-dipole interactions, which have been neglected in previous
calculations.
