“For muonic atoms, the Bohr-Weisskopf effect can account for half of the hyperfine structure interaction.”

“The nuclear interaction in muonic molecules can be treated as a perturbation using the smallness of the nuclear scattering amplitude in comparison with the molecular scale.”

“If such an experiment yields results similar to those of the muonic hydrogen one, Arrington says, then it's likely that new physics is at work.”
