Potential model calculation of proton-proton bremsstrahlung using the Paris potential

Journal Article · · Phys. Rev. C; (United States)
;

Cross sections and analyzing powers are calculated for proton-proton bremsstrahlung (pp..gamma..) using the Paris and extended Reid soft-core potentials. One pion exchange contributions have been added for partial waves with J-italic> or =6. Relativistic spin corrections, certain other relativistic corrections, and some Coulomb corrections have also been added. The calculation utilizes fully relativistic kinematics and is performed in the center of mass frame in order to put to zero the leading contribution of the double scattering terms. This is the first pp..gamma.. calculation to use one of the modern theoretically based nucleon-nucleon potentials. The results of this calculation are compared with experimental data, as well as older potential model and soft-photon approximation calculations. The off-shell behaviors of the Paris and extended Reid potentials are also investigated. We find that the analyzing powers are sensitive to details of the calculation. Asymmetry data are expected from a new TRIUMF pp..gamma.. experiment which will provide the first opportunity for a detailed comparison of such data with a modern potential model calculation.
