Simple Relation Between Proton Radius, Bohr Radius and Fine Structure Constant

Authors: Raji Heyrovska

The radius of the proton has aroused a lot interest in recent years, since the reported values vary from 0.8751 fm to 0.8335 fm, where fm = 10-15m. Here the author shows that the former CODATA value obtained for hydrogen can be related to the ground state Bohr radius for hydrogen and the fine structure constant by a simple equation. The latter lower value obtained using muons could be due to the differences in the reduced masses of hydrogen and muon
