- sevenless 10y agoFor protons, the muon-derived radius is 4% smaller than for the electron-derived radius. But for deuterium, the discrepancy is only 0.8%. Is there some obvious scaling argument why adding a neutron should reduce the anomalous effect by a factor of 5? Actually, why is it that the deuteron's charge radius is so more than 2x the proton's? It obviously doesn't work like you'd expect something volumetric to work.
