Abstract：
The high spin states of¹²⁹Ce have been populated via heavy-ion fusion evaporation reaction⁹⁶Mo (³⁷Cl, 1p3n)¹²⁹Ce. The comparison between the signature- andB(M1)-staggering defined by Hagemann and Hamamoto have been showed in the negative-parity band of¹²⁹Ce. The lifetimes and quadrupole momentsQ_tof the high spin states of¹²⁹Ce have been extracted from the line shape analyses using Doppler shift attenuation method (DSAM). The deformation parameters extracted through the solution of equations for quadrupole transition momentsQ_tand collective moments of inertiaJ_RR.
