摘　　要：The high spin states of 129Ce have been populated via heavy-ion fusion evaporation reaction 96Mo (37Cl, 1p3n) 129Ce. The γ-γ coincidence and intensity balance used to measure the B(M1;I →I-1)/B(E2;I → I-2) (the probability ratio of the dipole and quadrupole transition) in ν7/2[523] rotational band of 129Ce. And the energy splitting (△e ’) has been got through the experimental Routhians. The lifetimes and quadrupole moments Qt have been extracted from the lineshape analyses using DSAM. The deformation of the ν7/2[523] rotational band of 129Ce was extracted from the Qt and moment of inertia JRR.The high spin states of 129Ce have been populated via heavy-ion fusion evaporation reaction 96Mo (37Cl, 1p3n) 129Ce.
