WebThe most accurate charged pion mass measurements are based upon x-ray wavelength measurements for transitions in π − -mesonic atoms. The observed line is the blend of … Webis used with a pion mass of. π 0 mass = 264 m e = 135.0 MeV/c 2 the range obtained is Range = 0.73 x 10-15 m = 0.61 x classical proton radius.. This range is in the neighborhood of one fermi. When Hideki Yukawa was working on a theory of the strong force, he judged that the range of the nuclear force was about a fermi, and calculated that the exchange …
