Two independent calculations of proton-deuteron elastic scatteringobservables including Coulomb repulsion between the two protons are compared inthe proton lab energy region between 3 MeV and 65 MeV. The hadron dynamics isbased on the purely nucleonic charge-dependent AV18 potential. Calculations aredone both in coordinate space and momentum space. The coordinate-spacecalculations are based on a variational solution of the three-bodySchr\"odinger equation using a correlated hyperspherical expansion for the wavefunction. The momentum-space calculations proceed via the solution of theAlt-Grassberger-Sandhas equation using the screened Coulomb potential and therenormalization approach. Both methods agree within 1% on all observables,showing the reliability of both numerical techniques in that energy domain. Atenergies below three-body breakup threshold the coordinate-space method remainsfavored whereas at energies higher than 65 MeV the momentum-space approachseems to be more efficient.Comment: Submitted to Phys. Rev.
