Abstract High spin states in 137Ce have been studied by using the heavy-ion induced reaction 124Sn（18O, 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~ -60o in neighboring nuclei and probably originates from the five quasi-particle configuration vsl/2 [vh11/2]2 πg7/2 πh11/2. The characteristics of this oblate band have been discussed.
