Triaxial shape in Ce-129

The high spin states of Ce-129 have been populated via heavy-ion fusion evaporation reaction Mo-96 (Cl-37, 1p3n) Ce-129. The comparison between the signature- and B(M1)-staggering defined by Hagemann and Hamamoto have been showed in the negative-parity band of Ce-129. The lifetimes and quadrupole moments Q(t) of the high spin states of Ce-129 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 moments Q(t) and collective moments of inertia J(RR)
