Parameterization of the phase shift D33 for Pi-N Scattering
  From the partial wave analysis, the phase shift D33 of pion nucleon scattering containing the D(1232) resonance, corresponding to isospin I=3/2 and angular momentum J=3/2, has been parameterized over the energy range 1100 < W < 1375 MeV, using p-Pi+ data. The result of our parameterization shows good agreement in comparison with the available experimental data.
