摘要

High spin states in 138Ce have been investigated following heavy-ion induced reactions carried out at the China Institute of Atomic Energy,Beijing.Two collective rotational bands were established for the first time.These two bands show oblate deformation withγ=-60°and probably originate from the four quasiparticle configurationsπg7/2πh11/2Uvh11/2 vd3/2 andπg7/2Uπh11/2[vh11/2]2,respectively.These oblate bands exhibit strong M1 transitions,no signature splitting and different moments of inertia from those of prolate bands.
