Abstract
We give a critical discussion on different ways to determine the proton charge radius. It is demonstrated that the best results of its measurement can be obtained from evaluation of the Mainz data on the electron-proton elastic scattering, but the uncertainty has to be large by factor two. A review of the hydrogen Lamb shift experiments and the radius determination from them is also presented.
