TL;DR: The root-mean-square charge radius, rp, has been determined with an accuracy of 2 per cent by electron–proton scattering experiments, and the present most accurate value of rp (with an uncertainty of 1 per cent) is given by the CODATA compilation of physical constants.

TL;DR: Accurate knowledge of the charge and Zemach radii of the proton is essential, not only for understanding its structure but also as input for tests of bound-state quantum electrodynamics and its predictions for the energy levels of hydrogen.

TL;DR: Laser spectroscopy of the Lamb shift (2S-2P energy difference) in light muonic atoms or ions, in which one negative muon μ− is bound to a nucleus, has been performed as mentioned in this paper.
High-resolution laser resonances of antiprotonic helium in superfluid 4He
TL;DR: In this article , it was shown that when an exotic helium atom with a constituent antiproton is embedded into superfluid helium, its visible-wavelength spectral line retains a sub-gigahertz linewidth.
