Bremsstrahlung in p-p-collisions at an energy of 150 MeV

The differential cross-section for bremsstrahlung in p-p collisions at an energy of 150 MeV is calculated at the upper end of the photon spectrum. The only transition which is considered is the E2 transition between 1D2 and the 1S0 state. The Siegert theorem is used and the influence of the Coulomb force between the two protons is neglected.
