摘要
High spin states in ^(137) Ce have been studied by using the heavy-ion induced reaction ^(124)Sn(^(18) O, 5n) carried out at China Institute of Atomic Energy. Partial level scheme with spin up to (43/2^(-)), including a high spin collective rotational band observed for the first time, has been established. The collective band shows the properties similar to those oblate bands with γ ~-60° in neighboring nuclei and probably originates from the five quasi-particle configuration νs_(1/2)■ [vh_(11/2)]^(2)π9_(7/2)■ πh_(11/2). The characteristics of this oblate band have been discussed.
