Abstract

The high spin states of ¹³⁶Ce (Z = 58) were investigated via ¹²⁴Sn(¹⁶O, 4n)¹³⁶Ce fusion evaporation reaction at MeV. The γ-γ coincidence technique is used for placing the γ-transitions in the level scheme. The spin and parity of the levels have been assigned on the basis of results of the angular correlation and linear polarisation measurements, respectively. The bands based on the yrast 10⁺ isomeric state and the non-yrast 10⁺ state have been established. The structures of these bands are also compared with the band structures of the neighbouring nuclei.
