Abstract High-energy γ-rays from the deexcitation of giant dipole resonance have been measured from the decay of compound nucleus ¹³²Ce^* formed by the ¹⁶O+¹¹⁶Sn reaction at an incident particle energy of 85.0MeV of ¹⁶O. The γ-ray multiplicity distribution of this reaction is calibrated with a multiplicity filter composed of 14 hexagonal BGO crystals. The shape evolution of the ¹³²Ce^* has been studied as a function of spin. The results reveal that the deformation parameter of prolate ¹³²Ce reduces when spin increases.
