New transitions and levels in 148 Ce have been observed in a γ-γ-γ coincidence study from the spontaneous fission of 252 Cf with Gammasphere detector array. The ground band has been extended up to I π = 22 + , and side bands are extended with I = 2 stretched transitions and I = 1 crossing transitions. The observed level scheme is interpreted in terms of possible octupole correlations. Two sets of interwined positive-and negativeparity bands with the simplex quantum numbers s = ±1 are suggested. The results of B(E1)/B(E2) branching ratios indicate that the octupole correlations in 148 Ce are strong.
