By 22 MeV proton inelastic scattering at the forward angle of 10°, the orbital character of new low-lying M1 excitation states in 160Gd has been verified. At the same time, several new energy levels of 160Gd are observed, and values of spin, parity and deformation length for two new energy levels with excitation energies of 2.558 and 2.607 MeV are given via collective distorted wave Born approximation calculations.

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 85.0 MeV 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.
