Abstract：
The high spin states of¹²⁹Ce have been populated via heavy-ion fusion evaporation reaction⁹⁶Mo (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 of¹²⁹Ce. And the energy splitting (Δe′) has been got through the experimental Routhians. The lifetimes and quadrupole moments Q_thave been extracted from the lineshape analyses using DSAM. The deformation of the ν7/2[523] rotational band of¹²⁹Ce was extracted from the Q_tand moment of inertia J_RR.
