The Proton-Proton Interaction [PDF]

Physical Review, 1950
This paper presents a phenomenological analysis of the proton-proton scattering observed at 32 and 340 Mev in terms of static nuclear potentials. Comparison of these results with the neutron-proton scattering at 40, 90, and 280 Mev analyzed previously indicates that nuclear forces are not charge independent. In particular, there is definite evidence in
