At first, considering the inhomogeneous part of Faddeev equation, which is a valid approximation in high and intermediate energles, we present the Faddeev equation as a function of vector Jacobi momenta and spin and isospin quantum numbers. In this new formulation, a three-dimensional representation of deuteron wave function instead of its partial wave representation. Then, this equation is rewritten in suitable coordinate system as a function of vector magnitudes and angles between them for numerical calculation. Finally, by applying the Bonn-B potential the proton-deuteron breakup scattering cross section is calculated and the results are compared with the experimental data.
