Radii of Electron, Proton, Neutron, Deuteron and Helium Nucleus

Authors: Gang Chen, Tianman Chen, Tianyi Chen

In our previous papers, we once gave formulas and value for the classical electron radius (re=2.81794032658(43) fm) and the proton charge radius. In this paper, we give new and more reasonable formulas and values for the proton charge radius, and the values should be different according to the three different measurement methods, so we give three values, i.e., rp/H=0.8330977868 fm, rp/H-μ=0.8419605292 fm and rp/e=0.8311047299 fm. In addition, we also give formulas and values for the neutron charge radius (rn/e=0.3312876729 fm), the deuteron charge radius (rd/D=2.142299805 fm, rd/D-μ=2.125297426 fm and rd/e=2.127921954), the neutron equivalent radius in deuteron (rn/D=1.309202018 fm) and the charge radius of helium nucleus (α particle) (rα/He= 1.688564465 fm, rα/He-μ= 1.678205173 fm and rα/e=1.681409530).
