By considering the effect of  resonance in the  invariant mass spectra comes fromreaction, and a comparison between theoretical spectra and Braun’s data, we found the best theoretical spectrum fitted to the experimental data. The energy and width of  resonance state are respectively extracted  and  from the fitting process.
