PROTON-INDUCED DEUTERON BREAKUP REACTION H-2 (P, PP)N

The ''screening and renormalization'' approach allows for a mathematic ally correct incorporation, in three-body scattering theory, of the lo ng-ranged Coulomb interaction between charged particles. It is based o n first calculating the transition amplitudes using screened Coulomb p otentials. Then, after renormalization the zero-screening limit, leadi ng to the amplitudes pertaining to unscreened Coulomb potentials, is p erformed numerically. Within this formalism the proton-induced breakup of deuterons is investigated, with the Coulomb repulsion between the two protons taken into account. Kinematically complete differential cr oss sections in various kinematic configurations are calculated and co mpared with the results of an identical calculation but for the neutro n-induced reaction. In this way information on the size of the Coulomb effects in the proton-deuteron reaction can be extracted. Comparison is made with experimental data at 13.0 MeV projectile energy. In addit ion, the quality of approximate ways of including the Coulomb interact ion is studied.
