  The phase shift of pion nucleon elastic scattering D33, corresponding to
isospin I=3/2 and angular momentum J=3/2, has been parameterized over the range
1100 < W < 1375 MeV, using the single channel p Pi+ data from CNS-DAC. By
employing our four parameters formula, the pole positions of corresponding to
the Delta(1232) resonance are then identified.
