To determine the shape of 132Ba Coulomb excitation measurement has been performed at U-200P cyclotron at Heavy Ion Laboratory, University of Warsaw, Poland. A 32S beam of ~90 MeV energy has been bombarded on enriched 132Ba-target to Coulomb excite the latter nuclei. EAGLE gamma-ray spectrometer consisting of 15 single crystal HPGe detectors has been used to detect the deexcited gamma-rays from Coulomb excited Ba nuclei. The data has been collected using Particle-gamma coincidence technique for a period of seven days. The back scattered projectiles have been identified with 48 PiN diodes of 0.5 X 0.5 cm2 active area mounted in a scattering chamber of ~5 cm radius called as ‘Munich chamber’. The energy states up to ~1127 keV energy have been populated in the interested 132Ba isotope. The preliminary results of the data analysis are presented here.
