The Scattering of Protons by Protons

Physical Review, 1936
Our measurements of proton-proton scattering during 1936 established the existence of large nuclear forces between protons at close distances, in addition to the usual Coulomb forces. These nuclear forces give rise to scattering in excess of the Coulomb prediction, appreciable at 700 kilovolts and very marked at 900 kv. In the energy region between 200

Proton-proton bremsstrahlung

AIP Conference Proceedings, 1978
A field theoretic calculation of ppγ is presented. Strong interactions are taken into account to second order. Apart form the contribution of OBE external exmission, the contributions of the ω‐radiative‐decay process and Δ excitation are calculated.

Proton-Proton Interaction

Physical Review Letters, 1961
A model for p-p interactions below 350 Mev is studied, which contains a boundary condition to represent the shortrange potential, and a fourth order static perturbative tail for the long-range interaction. The scattering phase shifts and wave functions are found for various energies and quantum states.
