Abstract：
To check the feasibility of deep inelastic heavy-ion reactions in populating the high-spin states in Z≈56,N≈80 nuclei, a test experiment has been carried out by using the reaction of 410 MeV ⁸²Se+^natBa. γ-γ coincidence measurements have been performed using in-beam γ spectroscopy techniques. Population cross-sections of excited states in both target-like fragments and projectile-like fragments have been estimated. New γ transitions were identified in several target-like fragments. A new level scheme including five new levels has been established for ¹³⁶Ba. The preliminary results show that deep inelastic heavy-ion reactions are very promising for populating the excited states in the Z≈56,N≈80 region.
